I am looking at the prices on eBay for "China iPhone 3GS 32GB unlocked" and I'm wondering if anyone here has experience using one of these purely as an iPod? Is it possible? I don't want or need the cell service. The big draw for me is the compass/GPS feature and the way cool StarMap Pro app. I wasn't sure if I should ask this in the iPhone or iPod forum so mods if this should be in the iPod forum so be it.
