Something sad and painful happened yesterday – I accidentally wiped out all contacts and calender entries in my Dopod.
Ouch.
And to make things worst, I also deleted the backup.
Double Ouch.
So now I’ve trying to reconstruct items but its not going to be easy. I can already foresee alot of phone numbers gone forever. The calender part will be less tricky.
Losing data can be painful.

No such problems if PPCPimBackup had been used. I feel for your lost.
I feel your pain. Lesson learnt I hope =)
