I had my original iPhone replaced a couple of months back because it had a faulty multi touch screen. Great, i thought, but the replacement I got seems to have poorer battery life and it is constantly dropping its wifi connection in several locations, two of which are having wireless supplied by AEBS, and one by an iMac sharing via airport. I've tried everything I can think of to no avail and was hoping 2.0 might fix the problem, but it hasn't. Anyone else have this problem? Could it be a hardware issue?
