I ordered this kid to replace my iPhone 3GS battery: http://www.amazon.com/6279Q595-Replacement-Battery-1600mah-iphone/dp/B001UGAX82 The whole replacement went smoothly, and it booted up the first time I tried. However, after being on for around 3-6 minutes, my phone rebooted. It didn't go into recovery mode, just a normal reboot (without me doing anything obviously). And then again, after around 3-6 minutes after the first reboot, it does it again. So I decided to reinstall the firmware, and then I got error 29, so I used iRecovery to get it out of recovery mode (error 29 means hardware error, just an unknown battery). I'm a little worried though, because there was a very small gold looking tab on the side of the inside of the phone that broke off. It looked like a tab to keep the logic board down and not moving, because it didn't look like it was touching any contacts. I don't know where that tab went though. It's not that GSM connection thing either, because I can make and receive calls fine, it's just rebooting a lot (but it doesn't go into recovery mode unless I restore). Any suggestions? Is that gold tab of any significance? If so, how could I fix it? Thank you so much! Edit: In case this is of any significance, I used the guide on iFixit.
