Ok so the 3GS **** the bed this weekend and I'm using a GoPhone that I refuse to use for a second longer. I found a iPhone 4 for $350 on craigslist. I feel this will hold me over till January when the iPhone 5s aren't such a novelty and can be found. It will make for a good backup phone as well. Just want to make sure I'm not a idiot for doing this. I can't go another day without an iPhone and while I plan on getting the 5 early next year.... this will feel like a brand new toy compared to the 3GS. thoughts....?
