I Dont Know If Anyone Else Has This Problem But My 3GS Is Also Jailbroken (32GB) And Is Running Fast Where As My 3G Is Th Oppiste Is There Any Cure/Fix To This?
Umm, my best guess would be to wipe it clean, then re-sync everything back on to it. But you could try holding down the menu button for a few seconds, i think on iphone thats the rest when it freezes and this might cure it.
