Here is the basic story: I am 15 and want an iPhone desperately. I am also currently hosting in Cydia and am constantly working on iPod Touch modifications. But I really want to take a step up from that. Believe it or not, I am currently writing simple applications and modifications. I only have one problem: I only have an iPod Touch that is primarily used for testing all of my apps and mods. It is currently giving me some issues, though, because some of my mods have bugs, and I have yet to discover what is causing the constant crashing. But this is my real question: Can I buy an iPhone (2g or 3G, doesn't matter), and still use it without any SIM card? Basically what I am saying, it would be an iPod Touch with a camera and Bluetooth. Is it worth it? Also: Yes, I consider myself to be an Apple Fanboy.
