A little while back I purchased the Wififofum app from the itunes store. It's a wifi stumbler that was banned a little while ago, and somewhere along the way I must have deleted it from my itunes directory. Is there any way to get this application back onto my iphone at this point without jailbreaking it? I've found an .ipa file for this app, but when I try to sync it tells me it couldn't because an unknown error occurred. I'd really like to keep my iphone legit and have this app at the same time. Thanks.
