i have a razor i just swap the sim to iphone..so if i get a smart fone from t-mobil and sing up for 19.99$ t-mobli and pop that sim on my iphone my speed will still be pretty much the same..i guess it dont matter its all same sim card just the phone you have ..?
right now i get about 80+kb on ok place..but when im out i get about 100+kb..is that good?
