Today’s the day that’s been rumored for T-Mobile’s release of the BlackBerry 8320, which has now been confirmed by a RIM announcement. The online store is stocked, and a few folks have said that they’ve been able to find the gold and titanium-clad BlackBerrys in their local T-Mobile outlet. Boy Genius already has his hands on one (go figure), and has done a side-by-side browser battle with the BlackBerry 8300 to test out EDGE versus Wi-Fi speeds. The results are interesting, to say the least. He makes a solid case that Wi-Fi for data transfer isn’t that big of a deal, so unless you have UMA support, the BlackBerry 8320 won’t rock your socks.
