Not a whole lot to go on for this rumor, but BGR just posted a two-liner saying that a source of theirs from Samsung told them " they’re working with T-Mobile on a “major” product launch for the month of July."  Could it be the Samsung Galaxy S?  Perhaps the I897 with T-Mobile's 3G frequencies?  What about that spiffy HSDPA+ goodness available in some markets?  All of the above sound great to me!  What do you guys think?
