Probably this question has been asked, but couldn't find anything after searching... I am interested in an iPhone 3Gs, but don't want/need a cell plan. I only plan to use Wi-Fi, and never make cell calls (I'm a verizon customer, if you care). Reasons the iPod touch doesn't meet my needs: no camera (and the video cam in the nano doesn't take stills). No GPS. So in theory, could I buy a used iPhone 3Gs on craigslist sometime in the future, never use a calling plan, but continue to use the iPhone as an iPod touch BUT with GPS functionality and a camera? Would I still be able to download apps, etc, or will Apple lock it down if it's not on the cell network?
