Your pal has always wanted that $20 app for his iPad but could never bring himself to splurge. This Christmas, give him the app he's always wanted via the App Store. If you don't know what to get your bud, take a look around the Top Paid Apps charts for some good ideas. You can get "Grand Theft Auto: San Andreas" for $6.99. Any paid title in the iOS app store can be given as a gift, and Apple provides seven different e-wrappers from which to choose.
