I checked the search and got nothing good or current on this topic. I'm curious as to whether or not it's possible to fake a phone number on my iPod touch. I don't mean for things with VOiP or anything like that- I mean seriously convince my iPod and applications running on it that it's an iPhone with a number. I think it would be really cool to be able to use a mobilesubstrate extension for this, maybe set the number as an AIM account, email address, or Google Voice number. It could be used with iRealSMS and other things like that. btw: No, I will not get an iPhone for this, don't waste your time telling me that. I just want this for use on wifi.
