Hasta La Gadget!

By now you’ve probably watched iFixit’s recent iPad 2 teardown video several times while drooling profusely, but we just know you’re itching to find out what’s different with the innards of the WiFi-only, GSM, and CDMA versions. Well once again, iFixit’s got you covered — via an “exceptionally cool” user-contributed post, this time. A grand total of three iPad 2s were sacrificed in this round, revealing variations in case design, antenna count, WWAN board layout, radio chipset choices, and headphone jack assemblies. Besides clearly visible changes like the black antenna window on the 3G models and the microSIM slot on the GSM version, it’s interesting to note that Apple made the same design choices with the iPad 2 and the iPhone 4. The CDMA model features an additional antenna over its GSM sibling, and uses a Qualcomm Gobi dual-mode radio which supports both CDMA and GSM — the latter being unused — along with an integrated GPS receiver, just like the iPhone 4 for Verizon. The GSM version, meanwhile, uses an Infineon chipset for GSM and a separate Broadcom module for GPS, just like the global iPhone 4. Follow the source link below for more sordid details plus high-resolution pictures.

Smartphones continue to improve in the “smart” areas: better screens, faster processors, more memory, etc., but there’s not been a lot of innovation in the phone aspect of those devices. HD voice technology can change that, but since its introduction in 2009, hi-fi calling was only available on GSM networks… until now. Ericsson has just made the first HD voice call via CDMA — made possible by a new Enhanced Variable Rate Codec Narrowband-Wideband (EVRC-NW for the awkward acronym-loving crowd). The codec delivers sound in the 50Hz – 7000Hz range, which makes traditional calls limited to the 300Hz – 3400Hz spectrum sound like they’re coming from a drive-thru attendant at your local Mickey D’s. So far, the tech’s limited to the lab, but here’s hoping Ericsson lets it roam free to deliver the dulcet tones of our friends and family sooner rather than later.

It ain’t as crazy as you may think. If you’ll recall, we actually heard last month that Deutsche Telekom was mulling the idea of spinning off T-Mobile USA from its portfolio, and now it looks as if one carrier in particular is interested. According to the inimitable “people with knowledge of the matter,” Bloomberg Businessweek is reporting that Deutsche Telekom has gone ahead with talks to “sell its T-Mobile USA unit to Sprint in exchange for a major stake in the combined entity.” Granted, there’s no guarantees at this point that the two will actually reach a deal that sits well with both boards, and up until now, they haven’t been able to come to terms with T-Mob’s valuation. As the story goes, Deutsche Telekom has purportedly said that it could sell “all or part of the US business, and all options are open.” Meanwhile, Sprint’s remaining mum. A merger of these two would combine the number three and four players in America, but if that doesn’t pan out, T-Mobile USA may end up buying wireless spectrum from Clearwire as an alternative. We’re hearing that an outright sale of T-Mobile in the US is pretty much off of the table, but considering just how many backroom talks are apparently going on in both camps, we won’t be surprised until they tell us to be.

We knew good and well that both Verizon Wireless and AT&T would be getting their own 3G iPad 2, and while the latter is still trumpeting the original iPad on its site, VZW has gone ahead and put up a placeholder for what’s next. A scant four months after the first iPad hit Verizon airwaves (by way of a MiFi), the “thinner, lighter, faster and FaceTime-equipped” model is just around the bend — complete with an embedded CDMA 3G module. Hit the source link if you’d like to be notified of updates, or just make sure to wake up on March 11th. Whatever’s easier for you.

With Sprint starting up its Windows Phone 7 adventure on March 20th with the HTC Arrive, Verizon is now said to be matching its CDMA competitor with its own offering, the HTC 7 Trophy. We already knew this particular handset would be coming to this particular network in “early 2011,” but now WinRumors has narrowed that down to a launch at some point in late March. Verizon’s announcement is expected as early as February 28th, this coming Monday, and we’re hearing the NoDo update — the one with copy and paste — should be preloaded on the device from the start. Should this solid-sounding rumor bear out as foretold, Microsoft should finally be on all US carriers by the start of April.

[Thanks, Mike]
