We try not to be an overly philosophical bunch, but we can't help but observe some interesting parallels between Motorola's industry-first demonstration of an EV-DO Rev. A to LTE handoff with the way the entire wireless world is progressing. Without a single major carrier win to its name, EV-DO's successor, UMB, seems poised to ride off into the sunset while current CDMA customers like Verizon plan migrations to the GSM-friendly LTE standard. Anyway, this little technical achievement will certainly set the minds of said CDMA customers at rest, knowing that its subscribers will one day be able to roam on data services between EV-DO Rev. A and LTE cells -- and considering that the transition period could last many years, that's an important capability to have. On an interesting side note, Alltel was on hand for the demo; they've not committed to any 4G technology, but we can say with certainty that they're at least considering LTE at this point.

While some companies are keeping their UMA trials under wraps -- or at least they're trying to -- Nokia's keeping no secrets in launching a 50-family test in its native Finland. Participants in the town of Oulu will receive Nokia's 6136 UMA clamshell (we're guessing there's no room for whining about form factor or case color here), and thanks to Oulu's "Pan Oulu" project, free WiFi hotspots around town make UMA a particularly compelling sell. The trial is currently scheduled to last at least two months, during which Nokia will be keeping a close eye on handoffs, performance over WiFi, and presumably anything else that's managed to dog UMA thus far. We might be reaching here, but we're kinda hoping at least a couple of those trial families do us all a big favor whine about the 6136's lack of Bluetooth.

It doesn't take an industry insider to notice that T-Mobile's been putting together plans for a UMA service to bridge their GSM network with public and home hotspots here in the States. We've also guessed that Samsung's T709 would be involved, and though we still don't have anything approaching an official confirmation, these pictures have filled in some blanks for us. Sent in by a handful of intrepid beta testers risking life and limb for the public good, we see here that the T709 looks to be T-Mobile's launch handset as expected, sporting a 1.3-megapixel camera, GSM 850 / 1800 / 1900 with EDGE, roughly 69MB usable flash, and media player. They have at least two routers in the works -- a Linksys and a D-Link -- though the only difference from your average 802.11b/g router appears to be the addition of a button to facilitate painless, secure hookup to your phone without entering a WEP / WPA key. Our respective tipsters report differeing experiences however: one said it works well, improves reception, and has no complaints; another said UMA performance leaves a lot to be desired, and besides draining battery juice at a breakneck pace (8-9 hours standby), voice quality is poor without perfect WiFi reception, and GSM / WiFi handoffs are currently a bit flaky with frequent dropouts. Of course, this is all still in beta and we'll reserve judgement until T-Mobile gives the signal -- which shouldn't be too terribly long, considering the beta materials have retail packaging -- but the T709 sadly lacks Bluetooth and any sort of memory expansion, meaning we're already in a holding pattern for second-generation devices.
