BACK STORY: Went through a lot of trouble with Apple and they sent us a new iPhone... Water damage included. Go figure. They said we could keep the phone at no extra charge and we would get a replacement phone. Surprise! So here we are with an extra phone and no way to use it. OH! It's not the new 3GS phone. Just the predecessor. THE QUESTION: My question is if there's a way to be able to use the phone (with the new 3.0 software) as just your basic jailbroken iPhone without network services (plays music, movies, maybe a game app or two, etc.). No expectations for compass, 3G internet, phone calls, yadda, yadda... Would like to be able to use it on WiFi though... CURRENTLY: I plug it into iTunes, but it demands a SIM card. If there's an answer out there I'd really like to hear it! Thanks for any help!
