For some reason I can't install/uninstall any apps on my iphone :S.

It was working fine till a few days back ... have summerboard, installer and minesweeper installed ...

why dont you use installer instead?

Mine stopped working yesterday after a week of working with no problems on two machines for a week. It stopped working (together with iTunes) after I tried plugging the iPhone dock into a regular Blackberry mini-usb charger to get the iPhone to charge. Anyway, a simple restart of the computer fixed the problem.

Rebooted ... still doesn't work !

Bumpppppppppppppppp
