Just wanted to announce my app here. http://www.SpoofApp.com. The installer source is http://www.spoofapp.com/source Anyways, SpoofApp in conjuction with a caller id spoofing provider (currently only Phone Gangster, with more to follow real soon) allows you to make calls from your iPhone with any caller id number you want. It more or less allows you to use these service providers directly from your iphone, where normally you would have to call an 800 number or visit the providers website to make a call. It integrates with your contacts, and even offers built in voice changing (however at the moment, phone gangster doesnt offer it). Check it out and give me some feedback. Thanks - AL PS: this works on the iPod Touch too. You just have to put your cellphone number in the settings menu and calls will be routed to your cell.
