says for 8100, 8110, 8120, 8130 but they are the same on the 88xx series World Edition and the 83xx Curve as well. I don't know about the Bold yet I havenot got to take one out yet.
No problem. My wife is going threw them one a month. I don't know how she locks them up. She does play with her phone all day, games and stuff that I don't. I have not found a game I like enough to play on my BB yet LOL.
