Questions on upgrading OS inside BES
Looking for some info on this one:
I have an 8830 on Sprint and am currently running 4.2.2.123. I know there is an upgrade for 4.2.2.265. I am on a BES for work and am looking for guidance on the following:
1) Will upgrading affect any functions (email, calendar, contacts synchronizing) or will I lose my BES Enterprise Activation? I don't have the password I used in the original activation and getting help from IT can be difficult. Not really their fault, their just very busy. We have close to 4,000 employees.
2) Is it ok to go straight to the later OS or do I need to do each successive OS upgrade. I'm definitely a newbie but love my blackberry
Any help would be greatly appreciated
