Hey guys/girls. Question. I bought my phone 3G once they came out and of the course the 90 day is out and I am having hardware issues. A few months ago I got a new glass put in from a store down the street. The glass looks good and now I am having lock up isses. I tried resetting phone and still locking up here and there. They hardware warrenty expires in May 2010.

I called Apple and they want to send me a replacement for $500 hold on my card. Once they get the old one back they will releace the hold. Does Apple look at the old phone and determine that I open the phone up and then charge me $500 for messing with the old phone?
How does that work. I know the glass people did not do anything wrong, they have done a lot my friends glasses before.

Thanks all!
