Im using a blackberry 9320 and i have low storage. In my applications I have many apps that I dont use, I want to check if they are ok to delete. I dont use -

Amazon Mp3 music store
Blackberry maps (will this affect my location services if i delete it?)
Brickbreaker (game)
Word Mole (game)

Any other suggested apps to delete?

Ive also already deleted a few apps from my world on blackberry app world that I dont use. Any other ideas to get better storage?
