Hi, I bought a new unlocked iphone about 2 weeks ago ive been using it. I'm happy with it except that I am starting to have some problems. Using the installer (which was already installed in it) I downloaded the program customize and changed some stuff which I have not been able to change back to its default for example: instead of slide to unlock its stuck on slide meeee. I just put that for fun and now its stuck. My installer has been giving me trouble I downloaded an update 2 days ago and till now it just opens and closes back by itself. I tried reseting all settings it didnt work only deleted my music and contacts but all my applications are still there.

If anyone knows what I can do please let me know if you think its better to update to 1.1.2 I will but please someone show me a guide or something because im a little new to all of this.
