This is the best OS after trying various operating systems, the latest OS which is 822 has a bug where your ringtones would be come silent all of a sudden no matter what you did, battery pulls don't help, increasing the volume of the profile doesnt help..
So I've been running OS 771 for a while and find it has very good battery life, good reception / signal quality, almost no memory leaks, and no bugs to mention, even the lock key works smoothly as soon as u press unlike how u need to press it a few times and hold it on 822
Formatting the phone is better. It's not that hard to restore your apps you know.
Also, make sure you only select the components you want and not install everything to save some space.
Make sure you do not install 126.96.36.1992 it is the worst OS ever and it has the silent ringtone bug which has been admitted by RIM!
Install 188.8.131.521 it's the best with good battery life, fast speed, and good reception quality.
