I got my P910i about 2 weeks ago. Currently i have R4A02 and the newer from SE site is the R4A10.
So i want to backup, upgrade, format and restore the phone. BUT:
i want to backup also sms, MMS, all contacts, calnedar and Tasks. If i make a backup from the software (latest available) will i have these? They are important to me and wouldn't wanna lose them.
It's my only step before proceeding to upgrade. Thanx in advance for any replies.
