I don't like the idea of getting something new if there is a chance to fix something old which suits my needs. My wife's iphone 3g had a tired battery. I looked all over on-line then found your sight. I had a good feeling based on the "feel" of the site. I ordered a battery and suction cup. Replaced the battery but wished I had purchased a "spudger" too. The most amazing thing is that the phone worked afterwards!
