iphone 3g slow?

[SolidSnake]

sup everyone

lately my iphone has been going really slow.... when i open contacts and scroll down it lags badly. Even if i write a sms the key board is so slow, i type a word and 30 seconds later it will appear.

Does anyone else have this problem? is there a fix? Thanks

i got a few friends who have the iphone 3g too they dont seem to have that problem at all.... maybe i should reinstall the firmware?
