How do i uninstall skype from ipad 2?

keep your finger on skype icon for at least 2 seconds, the icon begin "vibrating" and an "x"on left upper corner appears... just click on the "x" and the skype is disinstalled...

pay attention that if you have skype on itunes, and the sync is set as automatically, the skype will re-installed again automatically

You uninstall it like you do any other app you've downloaded.

I suggest you read the manual: http://support.apple.com/manuals/

Hold & Press On The Skype App & Wait Until A Red X Pop Up In The Left Corner Of The App & Press It & Will Ask If You're Sure You Want To Uninstall
