I've just installed Revo4 today, and was loving it, however, I just went to change from Shade of Dusk theme to the ICS theme whilst at the same time changing the boot animation and upon restarting the phone icon and my contacts icon have changed. The phone icon is now a folder and the contacts icon is now the arrow which appears when you join contacts. I get a message The process android.process.acore has stopped unexpectedly and a force close button repeatedly when I try and open either. Anyone got any ideas? I hope I haven't ruined my phone.
