I downloaded the Skype app yesterday and the icon automatically appeared where all the other apps go. Do you mean you want it down at the bottom of the main screen beside the mail, photo, safari etc icons? If so, hold the skype icon until it jiggles then drag it down to the bottom of the home screen with the other main icons. Click the home button again to stop the jiggling.
Yes, my same question? Are you sure that Skype was installed on your iPad or just on your computer? Check the Apps section in iTunes on your computer and determine if you need to sync? Just asking - I have Skype on my iPad2 and an icon should have been placed on your home screen. Please post back if you resolve the issue - good luck!
