Rumors have it that AT&T has been reallocating its EDGE service to the weaker 1900MHz band this move is supposed to improve 3G strength in HSPA devices.
I currently am relying on EDGE service with my first generation iPhone and even though I live in a small city of 30,000 or so I haven’t seen any signal issues even when I’m miles outside of town.
It’s odd that AT&T would decide to do this now, unless they are going to begin really pushing 3G coverage to more and more areas and (obviously) eventually phasing out 2G altogether.
I have a feeling that there won’t be too many people affected by this, hopefully AT&T will be smart enough to know where this strategy would work and where it wouldn’t be a good idea, but let’s face it, AT&T has made some mistakes in the past and will obviously make more in the future.
