I have the original 8 gb iphone. It is a applecare replacement that is about 2 months old. Since I installed 3.0 there are some issues. I am wondering if it is the software or the phone? 1. wifi reception goes in and out. The range has decreased and I loose signal, have to exit and re enter to get wifi back. 2. when I charge the phone or sync it, when I remove the cable I loose the clicking noise from turning on and off, pressing keys, ect. If I shut the phone down and restart it, I get the noises back until I hook it up again. 3. Voice signal and reception is not as good as it was. Should I have the phone swapped out or is this software related? Thanks for your advice!
