do they monitor it that closely?
what do u tink the 4g is gonna be like because the 3gs wasn't that major!
I disagree, the speed increase in the 3GS over 3G is a huge factor.
As stated, Apple is being forced to stay competitive so they will have to likely improve the speed of the phone again, plus open up alot of things previously restricted.
They will likely upgrade the GPS functions as the 3GS has poor GPS ability, likely fix the Wifi issues hitting both vanilla and JB phones plus I expect a whole new look to the phone firmware, something fresh including built in lockscreen themes and possibly a variety of application launchers.
