We all know the iPhone 5 is coming out later this year, and i want to add to my Apple collection with an iPhone. I don't have enough $$ to get an iPhone 4, but the 3GS would work perfectly. But the question bugs me: What if the iPhone 4 takes a good drop in price, as the 3GS did when the iPhone 4 came out? I'm not sure on whether or not to buy it or wait and see, haha. Thoughts? Thanks!
