Is there anybody who tried upgrading from Android 2.2 on this device recently? Or do you consider it a wise decision in terms of risks / gains involved?
I found tutorials that seem pretty up to date:

You have to take into consideration that the 4.1 system you'd be installing isnt a stock build, it is a ROM created by a developer. Cyanogenmod is generally pretty stable, but you would want to do your homework at the XDA Developers site to determine if there are any bugs or known issues, or how the performance of 4.1 is on your device by reading users' reviews.
This would also require you to root your phone, which may invalidate your warranty, which is another consideration.
