Hope you're having great time.
I just wanted to ask a few questions about the OS upgrade.
Actually, I'm very conscious about my phone, so I needed to ask all these before I upgrade my phone.
If I upgrade My Blackberry Curve 8520 from OS Version: 126.96.36.1994. To OS: 5.0.x.xx (given in the sticky threads).
Will It work without any flaws?
Or will I get any errors while the upgrade or loading?
And if I get any errors (maybe), what do I do to fix them?
What if my phone gets useless?
Will I be able to downgrade to my current OS?
Will my apps, memos and everything be automatically backed up? Or do I have to backup manually?
And how do we back up the apps?
