Thanks in advance for your help! I have a non-rooted DInc. My HTC Mail application looks to be 93MB. I only have one email account setup, with a total of 5 messages. I've deleted all trash and sent mail items...yet I cannot get the application size total to drop at all. I've cleared the cache too. Ultimately I know that this is causing the dreaded "Application Data Space Low" issues I have periodically. I'm just wondering if I'm missing a way to delete data that is getting "stuck" on the phone someplace and not truly being deleted? Ideas? Thanks again!
