I just pre-ordered mine from the UK and I was wondering if I will able to use it on Tmobile's 3g in the US. I am so confused about all the frequencies! I would hate it if I have to stick with using EDGE on it. Also I did a little snooping around and it seems like the galaxy S will be coming to the US later this year...on all 4 major carriers? So is it correct to assume that the phone will work on Tmobile 3g or are they going to sell different carrier exclusive models so that it will work on each individual network?
