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 22.214.171.1242 it is the worst OS ever and it has the silent ringtone bug which has been admitted by RIM!
Install 126.96.36.1991 it's the best with good battery life, fast speed, and good reception quality.
