I have a 9000 that is running OS4 and would like to upgrade to OS5, but I would like to perform a fresh install. I would like to remove installed third party applications. Should I use JL_Cmder to format my 9000 or just perform a normal upgrade? I read that I should not use JL_Cmder to format my 9000 if it is working fine. Any suggestions?

Thanks!

For a clean install I use JL_cmder to completely remove OS then load new OS

For info on using Jl_cmdr, see the FAQ. There are two articles there that should help.

Is it recommended to use use JL_Cmder to "wipe" my 9000 if it is working fine? Is this similiar to formatting a hard drive and install a fresh OS for a computer?

My 9000 is working fine it is just a bit slow. My thought is that it will probably perform faster if I do a clean install of the latest OS.

Thanks!

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 5.0.0.822 it is the worst OS ever and it has the silent ringtone bug which has been admitted by RIM!

Install 5.0.0.771 it's the best with good battery life, fast speed, and good reception quality.

3) Wait for a few seconds till you get the confirmation that it was done.
