We already know that Samsung’s freshly-launched Galaxy Tab Android tablet will be hitting all major US carriers and now whispers are going around of the possible launch date of this device on the carriers. While the exact dates weren’t mentioned, the rumor claims that AT&T will be the first in the race, shipping the tablet in mid-October; Verizon’s EVDO model will be arriving in early November; Sprint’s Galaxy Tab will be shipping in mid-November; finally T-Mobile’s version of the tablet will be the last amongst of all them, though there hasn’t been a fixed date just yet. Apparently the goal is to have the Galaxy Tab shipped to all the major US carriers before the holidays, which does make sense.
