The wifi on my original iphone has began flaking out... oddly enough while warming up in front of a space heater I found that the wifi works perfectly when the phone is warm... but not at all when cold, and flaky when slightly warm (like fresh out of my pocket). what in the world is going on??!! luckily this thing is still under applecare. What are the chances that I will get a 3g replacement? I have restored the phone (without restoring a backup) with no luck... still functions in every way other than flaky wifi.
