I'm thinking of using it for fring, and I have a 1G iPod Touch, but it doesn't have a mic so what should I get? I want either iPod Touch 2G or 3G, possibly the iPhone 3G or 3G What do u think I should buy? Is the iPhone 3G, when compared to an Ipod touch, kinda like 2G iPod Touch?? And if I don't have a contract. Can I still use it like an iPod touch ?? What's the advantage of iPhone?? And if I unlock it wouldn't carrier will sue me or something bc it's illegal??
