So I was going to buy an unlocked iPhone 2G 8GB from one of my mom's friends' for $150 and just use it as an iPod touch with a camera and mic. But a couple hours ago a lightbulb went off in my head. I though, "why the hell don't I not just buy a cheap pre-paid phone that comes with a sim card or get a sim card." So if I did that would all the phone features like SMS and calling still work with the cellular service? And all the data stuff (Safari, Mail, Stocks, apps, etc) would all still work when connected to Wi-Fi, right? I was thinking of using either this sim or this sim, OR I may use the sim card that comes with this pre-paid T-Mobile phone. Thank you!
