I am wondering if anyone out there is using an iPhone with data only... I was hoping the new iPod Touch would follow the iPad's suit and add 3G but no such luck... I am thinking about getting an iPhone 4 unlocked (I live in Canada) and using it with data only... has any one tried this? I am wondering how badly nerfed it is... can you still make Facetime calls? Are there any other functions (besides making phone calls) that don't work properly? Thanks.
