i decided to get the iphone 4,and so far quite impressed.

Obviously the 1st thing i done was jailbroke it but when i have tried to theme it there seems to be a problem.

I have installed winterboard and then downloaded the theme/sms/keyboard etc etc that i want to use to theme it but when i select them my iphone resprings but nothing happens not 1 of the downloads have worked.

I have tried with summerboard turned both on and off but still nothing.

Anyone nar how to fix this?
