A few days ago, I tried to install an update for GTA:CTW (over 20 MB) at a wi-fi hotspot, but had to leave before the update could finish. Now the app is unusable, and my phone constantly asks for my iTunes password. I live out in the boonies - no wi-fi out here. If I delete the app from the phone and restore from iTunes, will my game progress be restored as well? I've never restored an app, so any advice would be appreciated!
