I just changed the battery in my daughters iPhone 3G. Pretty straight forward as I’ve done it a few times on other iphones (which all went ok!). The moment I started hers back up though, I got the dreaded “overheat” message with the big yellow triangle. There’s no signs of warmth at all, and it happened the moment it booted up - so I can only say it’s false. Any ideas? I might try just stripping it down again and putting it all back together to see if it’s a dirty connector etc. I did blow off everything when it was apart though.
Wheeee! Just love responding to myself. :) Got it figured out now. I’m an idiot evidently, and ordered the wrong battery. I must have just clicked on a wrong link, and ordered a battery for a 3GS, not a 3G (I knew it was a 3G!). So there ya go - at least everyone else can benefit from MY blunder. We now all know what happens when you try to install the wrong battery in the wrong phone. :)
