Remember that proof-of-concept you saw way back in June of last year? You know, that one involving SlingPlayer Mobile for iPhone? Here at Macworld, Sling Media is doing its darnedest to take the spotlight away from the looming Apple keynote by announcing that said app is almost ready for consumption. It'll be demonstrating a functional version in San Francisco, and it's planning to submit the software to Apple for certification sometime this quarter. In case you couldn't care less, it'll also unveil a prototype SlingPlayer for Mac HD, which will enable Mac-using Slingbox PRO-HD owners to stream high-def material to their Mac. As for the good stuff, pricing has yet to be determined for the SlingPlayer iPhone app, but the SlingPlayer for Mac HD will be made available gratis. Full release is after the break.

For those with a whiteboard full of Apple rumors, you'll been keenly aware of the fact that the whole iPhone Air terminology has been tossed around before in a joking manner. This, however, is not a joke. In fact, it's a very real KIRF, and it's possibly one of the most awesome we've ever seen. We mean, who'd ever want an iPhone nano when one could have -- wait for it -- the iPhone Air. Aside from clean, beautiful, streamlined edges, those fortunate enough to procure one from China will also find dual SIM card slots, an FM radio, Bluetooth, a multimedia player and a built-in camera. The KIRF game just got stepped up good fashion, and we love it.

The iPhone Dev-Team works in mysterious ways, but it also works in quick ways. Granted, the iPhone 3G's initial unlock took way longer than anyone would've liked, but when reports started surfacing that it wasn't working particularly well after the first beta release earlier in the week, they appear to have worked doubletime to get a better version into circulation. The release is now up to v0.9.4 -- still beta -- but if you tried the first cut and struggled, we'd suggest giving the new version a whirl.

So, it didn't quite land before midnight as some had hoped, but we're sure you were partying too hard to notice. The Dev-Team just launched its long-awaited iPhone 3G unlock, dubbed "yellowsn0w," and while they're still working out a few kinks (terming this release a 0.9 beta release), reports are already pouring in of successful unlocks. It's also been confirmed that this release will work with the iPhone's latest v2.2 firmware, and in fact requires that the phone be updated to v2.2 to run at all -- much to the chagrin of folks who've held off on that update at the Dev-Team's behest, we're sure, but hopefully all will soon be forgotten in the new year... already freer than the last! Hit up the read link for download instructions and caveats.

Update: Unfortunately, it seems yellowsn0w might be living up to its beta status, with plenty of commenters and others across the interwebs reporting problems getting "unlocked" iPhone 3Gs to pick up their preferred carrier. As always, proceed with caution, and prepare some loose papers that need weighting just in case.

Ever since the Dev-Team kinda sorta promised that they would have a neatly packaged iPhone 3G unlock ready for release by the year's end, we've all been waiting on pins and needles, counting down the moments until freedom was in hand yet again. Now, a cryptic message on the crew's blog has been followed up with a not-at-all secretive image (shown above), which shows that whatever magic they've got going on will work with the latest (v2.2) iPhone 3G firmware. According to a related writeup at yellowsn0w, we're clearly told that the unlock tool will be made available by midnight PST at the latest, though we're hoping those guys have their AM / PM mixed up -- otherwise, you might be waiting until noontime tomorrow. At any rate, now you've more than a day off and black eyed peas to look forward to tomorrow, right?

Ha, you or someone you love just paid full retail for an iPhone 3G a few days ago, didn't you? We've always heard that the best deals come after Christmas, but people just never learn. All smack talk aside, those who didn't get a new cellie under the tree, but did acquire a Benjamin or so courtesy of cash-stuffed holiday cards, can certainly score a big deal today. AT&T is now offering the 8GB iPhone 3G in refurbished form for just $99 with a two-year agreement, while the 16GB refurb is $199 on contract in either black or white. Call us crazy, but we don't foresee these hanging around in stock for too awfully long.

Gee, willickers. More App Store madness. In case you needed even more evidence that the whole approval process in Cupertino was in complete disarray, David Carnoy's "contemporary medical thriller" has been rejected from Apple's App Store twice now. The first time it was returned to sender due to a few bugs in the coding; the second time, it was rejected due to the inclusion of "obscene content." Despite all of this, certain apps like iFart and Pull My Finger are allowed to remain, though it stands to reason that those programs are just as "obscene" as a few dirty words and sexual innuendos. Alexandru Brie, a developer and one of the first publishers of e-books to the App Store, feels that "each of Apple's reviewers can interpret the obscene, pornographic or defamatory content clause in a different way." Clearly, he's right.

At long last, iPhone users who have grown increasingly frustrated by using Google Maps as their primary navigational tool can find relief... sort of. Available right now in the App Store, XRoad's G-Map application requires no internet connection whatsoever in order to function; rather, it packs oodles of maps into a 932MB package that covers most of western America and a few sporadic locales on the east. We're a bit baffled (and angered) by the not-at-all-comprehensive coverage, but we suppose we can expect updates to patch the gaps in the near future. It provides most of the same amenities you're used to seeing on real-deal GPS units, including POI editing, memo capabilities, location searching, etc. A word of caution, though: early reviews don't seem too stoked about it, so you may want to gloss it over good before hitting your card for $19.99.

We can't unlock ours for a few days yet, so why don't we sit back, relax, and watch the boys and girls at the Dev-Team shoehorn their iPhone 3G onto T-Mobile while we wait? Follow the break for all the nail-biting action!

Worried that some less-than-becoming activities are occurring on your son / daughter / SO's iPhone? Rather than just approaching them directly, Retina-X Studios' Mobile Spy can now be installed on Apple's handsets. Put simply, the software / service combo enables the account administrator to "implant an undetectable rat inside the iPhone; it then squeals to a server, which is accessible via the web." Mobile Spy logs SMS messages, inbound / outbound calls and call durations, and it does so for just $100 per year. Then again, we'd prefer to handle things the old fashioned, more medieval way, but to each his / her own.

We don't cover a lot of games on Engadget Mobile -- or a lot of apps, for that matter -- but every once in a while we get graced with a franchise that's bound to get readers unusually fired up. This time around it's the cult hit Katamari Damacy in its I Love Katamari form, hitting the iTunes App Store courtesy of publisher Namco. The concept -- rolling a giant ball of crap around town -- seems almost tailor-made for the iPhone's control method, but unfortunately, we're hearing that the current version is a little rough around the edges with frequent slowdowns once you get enough stuff sucked into the ball. The platform's young, the game's young, and we're hoping it gets better over time, but only the most diehard Katamari fans may want to bite on the $7.99 asking price at this point.

If Walmart's $197 iPhone 3G had you salivating, wait until you get ahold of this deal: AT&T has refurbished iPhone 3Gs in stock for a mere $150, effectively doubling your rice and ramen budget for the month should you take the plunge. AT&T claims the refurbs were returned within the 30 day trial period, are quality tested, and might be just a little scuffed up. If you're really feeling wild, there's also a 16GB refurb available for $250. Apple and AT&T are being a little shady on the warranty, stating "90 days or more," as opposed to the standard one year, but that's a risk you and your growling stomach are just going to have to take.

Well this has been a long time coming. It seems that the iPhone Dev-Team has finally done the impossible -- they've gone and unlocked the iPhone 3G. The hack isn't out yet (the team says they're shooting for a December 31st release), and it requires that you've got a baseband of 2.11.07 or earlier, but when it drops, the crew seems fairly confident it will result in freedom from carrier oppression. The team is packaging the app -- formerly codenamed "yellowsn0w" -- into a user-friendly app a la PwnageTool and QuickPwn. Of course, you know how this cat and mouse game goes by now, so don't be surprised when Jobs and company come calling with an update that adds toast making to the official menu, but breaks your breaks all over again.

There's something just a little skeezy about basing predictions for Important New Apple Products upon nasty renders of protective case mockups from China. Still, they've panned out astonishingly nicely before, so we'll just have to suck it up. iDealsChina is reporting that XSKN is not-so-secretly working on a silicone skin for the upcoming "Nano iPhone" (or, more likely, iPhone nano) a shorter, chubbier version of the iPhone 3G. According to iDealsChina sources, the phone will apparently sport EDGE data, but otherwise seems unsurprisingly identical in specs to its forebears, other than the obviously smaller screen. They're also saying Apple plans to sell these at high volumes for low prices at hip spots like Walmart, that the company will (naturally) be unveiling the new handset in January at Macworld, and even go so far as to say that leaked photos of the device should be surfacing in the next couple of days -- we'll be keeping our eyes peeled. Check out another couple of tantalizing case renders after the break.

After some rumblings this past March, Microsoft has now officially joined the iPhone development community with Seadragon Mobile, a free app that lets you "infinite zoom" gigapixel-sized images. Although Seadragon is available as a Silverlight application on the desktop, Microsoft isn't bringing Silverlight to the iPhone, so don't get your hopes up -- this is probably just a custom implementation. We're itching to see if the company has any more apps in the pipeline -- we'll wish for an Office editor, but expect a Minesweeper variant.
