We've heard things like this before without results, but The Inquirer is reporting that a reader was tipped off to TMO US 3G handsets and plans. That rep replied with a date of December 6th, citing internal docs. It's a thin thread to hang this rumor off of, but last September, T-Mobile won an auction for 2100 and 1700MHz bands covering 474 million people. One would hope they're pulling the trigger sooner or later on 3G. I mean, their attempts to blanket the country in Wi-Fi haven't exactly replaced EDGE. Probability guess-timate: 20%. [Inq]
@ElectricTool: Yes they most definetly will
So this means that all the new sidekicks, and the newer phones that work on 2100 and 1700 mhz would be 3G capable. Most of the t-mobile phones already use 1800mhz and 1900mhz so i'm guessing that when the 3G network comes out there will be a firmware upgrade for those phones that will be able to use 3G efficiently.
Hopefully the 3G network is rolled out soon like in January i've been suffering the slow sluggish speeds of t-mobile's EDGE network.
