I'm a huge iPhone fan, i just love it. But one common problem for iPhone users is the battery of iPhone is non-removable. At least it's no so easy to be removed. Sure you can just ask Apple to do this job for you, but it will cost you 90 dollars.
Let's find a much cheaper way. You could just buy a set of the Toolkit for iPhone, it just cost you 7.29 dollars, and it's shipping free. Just 7.29 dollars, you will get all you need to replace the battery of iPhone:
1. a 3.7V 1400mAh battery of course
2. a screwdriver
3. a case opener
4. a manual
Go and get it on DealExtreme.
