I also beleive that it has been said on pdaphonehome and other places that the SGH-i760 does not have the correct band (2100mhz???) to be able to receive 3G here in America on our available GSM networks (att, tmobile)
3G equals:
EVDO Rev0 or RevA on CDMA networks
UMTS / HSDPA / HSUPA on GSM networks
hopefully that clears things up a little...

Hey Miata. Thanks for jumping in so I don't have to continue just talking to myself
I though 3G=Rev A and maybe 2G=Rev 0. I knew they were both EVDO, one being EVDO Rev 0 (SCH-i760) and the other being EVDO Rev A (SGH-i760) but I wasn't sure or just thought Rev 0 was 2G or 2.5 perhaps?, but not 3rd Generation.
From what I understand Rev A is quite faster than Rev 0 even based on every day usage vs just the ideal conditions/best signal on paper/in theory. From what I read in the forum and elsewhere if the device doesn't have Rev A hardware, which I believe the SCH-i760 doesn't, then no firmware will help it. IF the hardware was Rev A upgradable then it can be done but all of what I read seemed to say that the CH-i760 couldn't do it. I could be wrong about that so you or someone else can correct me on that.
My understanding based on what I read about HSPA in wiki and elsewhere is that the US 3G merges the HSDPA and HSUPA on one frequency, and that AT&T is locked to 1900 (though I could be mistaking it for T-Mobile a locked only to 1900 instead) which the SGH-i760 uses. The bands pdadb.net lists for the SGH-i760 are Cellular Networks: GSM900, GSM1800,
GSM1900,
UMTS2100 so even if youre right in saying it needed 2100 then it aparrently has it. This is just my understanding of it, but after talking with different techs many times, AT&T several times, and reading online all of it seems to suggest it should work fine with AT&T or if one needs/wants to it, would work fine on T-Mobile as well. If anyone has better information on all of this do feel free to jump in and clarify it for us please. Thanks.
