To remove applications from your Blackberry 8330 such as Facebook or Myspace you would do the following:
1). From the Main Menu, choose the OPTIONS button
2). From the Options Page, choose the ADVANCED OPTIONS button
3). From the Advanced Options Page, choose the APPLICATIONS button
4). You should then see a Loading Bar that says "Building List", once this is complete you should get the full list of Applications on the phone.
5). You would then scroll down to the Application that you would like to remove and press the Menu button and there will be the DELETE option which will remove the Application from the phone.
I hope these steps help you with removing these applications from the phone.
Great Day & My Pleasure!
Take note that even though you remove these apps, they will still show an icon on your phone unless you hide the icon. When you phone gets service books pulled down to it these icons get put back on the phone, but they are icons only. The actual program isn't installed unless you go to the icon for that program and perform the install.
You will delete Myspace, but when you reboot your phone you are still going to have an icon for Myspace, don't worry though, it's gone.
