hey guys!! i might be getting an iPhone 3G. the old one, not the new one. im thinkin about selling my first gen iPod Touch for like 100 dollars maybe even cheaper and getting the iPhone while its still 99 bucks. does anyone know how long the iPhone will only be 99 bucks? i want to wait as long as possible before buying. and is it possible to unlock it so i can put it on Metro PCS? or another phone provider? and if i buy it at the Apple store do i have to set up an AT&T plan? thanks!!
