Hi, What's the actual value of a used, unlocked iPhone 3GS 32GB White (in good condition)? And what's the new price for a New one (that's unlocked)? What about getting one on craigslist/eBay etc.? Would it be worth than to upgrade than? Where are iPhones usually cheaper - in Miami (South Beach) or New York City as I will be traveling between those two destinations a couple of times in the near future... I have a well working cell phone but I'm thinking of getting one as a personal organizer/mini computer/game console but the majority of postings say to wait - gets me nervous Thanks in advance!!
