Been itching to find out when T-Mobile will be releasing its upcoming devices, such as the LG G-Slate, Dell Streak 7 and Samsung Vibrant 4G? Well, the good news is that leaked information has surfaced, giving us a pretty good idea of when to expect these devices. According to the leak, the G-Slate will be arriving on the 23rd of March while the Dell Streak 7 will be released on the 2nd of February and will be priced at $299.99. The Galaxy S 4G (which should be the Vibrant 4G) was given a February 23rd date, which isn’t that far off at all. Considering that we’re nearly at the end of January, it doesn’t seem like we’ll need to wait too much longer to get hold of these devices.
