OK, update time.
I did the back up and synced the files, and there was an OS update which I allowed the desktop to do, and now it all seems fine.
BBM is back!
Facebook is back!
Life, gets back to normal.
Thanks for looking and your ideas guys.
Ha ha! Now BBM has gone again!
Doing my head in now...
This made the BBM and Facebook icons return as normal.
Then an hour later, BBM said to upgrade on my BB screen and so I did (bad move) which moved BBM to 18.104.22.168 - now the Facebook remains working and icon is there, but the BBM has gone belly up again (there seems to be an issue on Beta Zone which says it needs installing 1 or 2 more extra times for the icon to appear). I have tried this 5 times but BBM still won't operate.
Can I use the desktop manager to "roll back" the phone to before the new updates since the OS update, i.e. the moments before I moved to BBM 22.214.171.124 - would this reset the phone to this mornings OS update where it worked again?
I have tried that. BBM 5, and back again to build 126.96.36.199 but still it doesn't work, and no matter which I try to add, the App World listing still says I have the 188.8.131.52 on...
