Backing up to memory card and then restoring afterwards seems to work well, with only a few settings and a handful of applications (low level utilities, Python apps) needing attention. This is the way I handled the v31 upgrade on my own N95 8GB, it being a relatively minor update, I figured that not a lot would change under the hood and so a complete restore would probably work....
Approximate changelog:
- Closing of the SDK security 'hack' for jailbreaking personal devices
- Minor bug fixes and cosmetic improvements
- Photo quality improvements (assuming same algorithm tweaks as for N95 classic v31...)
- Better browser stability and speed improvements
Any comments or additions?
