Thanks to a leaked slide, some rumored release dates for upcoming T-Mobile 4G devices have been cemented. First up is Dell's Streak 7, which is set to debut on February 2; that will be followed by the Galaxy S 4G on February 23, while the Honeycomb-sporting G-Slate won't be launching until March 23.
Also leaked were two promos for the Streak 7 that nail down an on-contract (presumably) price of $299 - a pretty good deal for two cores and 7 inches of screen real-estate. T-Mobile's 4G lineup isn't lacking for tablets, but a refreshed Galaxy S handset probably isn't going to turn heads when compared to HTC's Thunderbolt or Motorola's Atrix 4G. Hopefully the MWC will bring some new guns to T-Mobile's 4G phone arsenal.
