The old battery was dying very quickly. I would switch off 3G to save battery, but it would still die on my way to work :-(

I watch the video on the ifixit.com site and read the instructions before opening up my phone. It was not that difficult, but I had to be careful in getting the battery out and the connector back in its place.

When you're closing up your phone, first screw back the connector before putting the new battery into it's place. It's easier that way to get the small cable back into the phone.
