I would like to upgrade OS and it will be for the first time I would be be doing anything like this to my BB. Current platform is 2.5.0.30.
1. Please advise which OS version I can install directly
2. If I go to BB Manager and take backup, will take include everything. I don't wanna loose anything I currently have.
3. Should I save backup someplace else on my computer or let it be default setting.
Thanks for help.
