I have my iPhone 3g and the warranty is coming up to 1 year in the next week. I had my phone replaced about 4 months ago due to my volume button, although ever since i've had the new iPhone I only get 1 bar in my house where my old one got 4 bars, and it drops 2-4 calls a day. Do you think apple would replace the phone? I also have a lot of bugs with this 3g compared to my old 3g phone. When I press the home button to wake it it sometimes gives me the iPod control screen instead of the home screen even though I never listen to music and a few other little software bugs which I've only noticed with this phone.
