Home Screen Icons Missing
I had a problem with my Curve 8310 where all my home screen icons disappeared. I could get to the call log and have some choices there, but couldn't do much else. I spent 3 hours with ATT suppoort and after doing soft resets, hard resets, master resets, downgrading the OS from 4.5.305 to 4.5.183 (or whatever the numbers actually are) I was able to get the icons to show up. But a couple of the apps like ATT Music, Blackberry Setup and Settings only gave me a popup with an exclamation point and an OK button. I could not get them to work. My phone was out of warranty and the best they could say was "Time to get a new phone."
After checking the web I came across a reference to BBSak program in a forum on the Crackberry site. After downloading and installing it, I did a Wipe System, then installed the BB OS 4.5.305 again. The problems were COMPLETELY RESOLVED!
