I have a post week 40 16GB 3GS running 3.1.2 jailbroken with blackra1n RC3 (tethered jailbreak).
When I assign a picture to a contact the picture dissappears after a reboot, a respring, or if I do a "free ip memory" in SBSettings. Also if I attempt to change an existing picture, the change only lasts until I exit that particlar contact sheet, then it reverts to the old picture.
Has anyone else come across this, and if so have you found a fix?
