does the galaxy s support 3G on both t-mobile and at&t? the specs
say it does HSPA on 1900 and 2100mhz.
t-mobile uses 1700/2100mhz for 3G. the galaxy s only does 2100mhz. so what does this mean? can the galaxy s do 3G on t-mobile?
at&t uses 850mhz and 1900mhz for 3G. galaxy s only does 1900mhz. again, what does this mean? can the galaxy s do 3G on at&t?
this is a little confusing. sorry, i wish i knew more about 3G frequencies. someone please enlighten me. does 3G require operation on two frequencies, or does support for only one 3G frequency allow 3G data connections?
the reason i'm asking is that i'll be in singapore soon, and i might be able to buy a galaxy s, but i want to make sure i can use 3G in the US.
