My 6 year old son wanted to use our old iphone as an ipod , but the battery went dead after just an hour of play. $20 for a new battery is a lot less than a new ipod for a little fella.
repair was about 30 minutes with 2 kids hovering over me. old battery was difficult to pry out but we got it done. The new battery works great and little man is having fun with it. The repair guide is great on your site! Pretty fun tearing it open and seeing what is inside, then getting it back to work again.
have a few little cups on the table to put the 3 different sizes of screws in. make sure the sim card holder slides back in before putting it all back together.
