How do I gift an app from iTunes Store on my iPhone?
Currently this option is not available, you'll have to do it using iTunes on a computer.
How to use App gifting with iOS 6
"Currently, app gifting is not available from your iPhone, iPad, or iPod touch with iOS 6. However, you can gift iOS apps from the iTunes Store on a Mac or PC.
Note: You can continue to gift apps in iOS 5 and earlier."
TThis answered my question. I assume they will be "fixing" the issue then with IOS 6 or adding it down the road. When I go to the App Store on my Mac however it only brings up the app specific for the computer.....doesn't show the iPhone or iPad app that I'm trying to gift. Any more help in this regard???
