You can delete all of those applications and not impact the e-mail and phone capabilities. They can be deleted through Desktop Manager / Application Loader, which will show you the size of those apps. Remove the check mark.
thanks nj. i put the zen os on there so everytime i hook it up to my computer it will upload the default theme and delete my zen. i read that its okay to delete them from options->advanced options->applications and then click to delete. is that correct? thanks for your help.
I deleted the password keeper and brickbreaker lol
when I plugged it into desktop manager it doesn't show any of my applications except the ones I downloaded already. How do I remove brickbreaker, etc.?
