I've downloaded Tango Qik, and Skype from iTunes and synced them to my iTouch 4G with ios 4.3.2 several times and can't get it to work. when i click on it on my touch it opens for about 1 second then goes right back to the springboard. same thing with all 3 programs. iv'e tried downloading them again and reinstalling them several times with no luck. based on i tunes i need to have IOS 4.0+ so my IOS is good. Can't figure this out. Please Help
