yeah I was just about to say restore. It's weird I've never had such problems but after my first restore i noticed problems with weather, then did a restore which fixed that and found my key sounds were gone completely lolll.. restored a 3rd time and it's perfect apart from a "Error Download Failed" error on installer every now and again.
I put all my errors down to chatting on msn like an idiot during unlock/activate/jailbreak lol

3rd time i was patient and didnt touch any keys on my laptop and worked a treat.
Scarface have you installed anything recently before having the problems with swirly? - TRY UNINSTALLING A RECENT INSTALL before doing a restore - just a thought
