How to Free Up Memory on your BlackBerry Smartphone

First off, you want to be sure you have a memory card for your device.  One of the most important accessories you can buy – a memory card is priceless.  It gives you loads of room to store all those ringtones, videos and MP3s that would otherwise eat up your device memory.  If you don’t have a memory card, check out the wide selection in the ShopCrackberry.com store.
The overall and most obvious way to free up memory is to delete any applications on your device that you do not use.  To do this, from your BlackBerry home screen press the Menu key, then go to Options > Advanced Options > Applications
Free Up Memory!
  • Select the unused app and press the Menu key.  Then select Delete.
  • Reboot the device.
  • If you choose to delete anything, your device will restart and yield a higher File Free.
The next few things we can do to start freeing up memory are fairly simple as well:
Enable Content Compression: Go to Options > Security and enabled Content Compression, this will free up some space.
Set Keep Appointments to 15 Days: This won’t make a major difference but will definitely free up some space.
Delete the “Help” Application: Once you get the hang of your BlackBerry you don’t really need this app. Go to Options --> Applications, select Help and delete it.
Delete the Sample Video: Go to Options > Advanced Options > Applications.  Highlight BlackBerry Sample Video, press Menu and Delete.
Delete the Unused Languages: You will have an option to remove them from the Application Loader screen.
Delete BrickBreaker: Why you ask?  Well if you never seem to play it then it just takes up space – so lose it.
Delete Pictures: Delete any unwanted images or move them to your memory card.
Clean Up Browser Cookies and Cache: Start the mobile browser.  Press the Menu key and select Options > Cache Operations.  Clear History & Clear Cookies.

Remove Unused Apps: You can also remove any unused apps such as Tasks, Memo, BlackBerry Messenger etc. to free up space.  All of the standard apps can be removed from the Application Loader in the Desktop Manger.
Deleting Old Messages: Deleting SMS messages and emails will save space and reduce lag as well.  I tend to delete all my previous SMS messages every morning.
Limit Your Themes: Everyone wants to have a good choice of themes, but having only 1 or 2 at a time on your device will save lots of space.
