hi, i have found a 32gb verizon iPhone 4 for $270 on craigslist. i have seen pics and the phone is clean and in excellent condition with clean esn. now I'm very eager to buy this and the person is holding it for me while i make a decision. I'm wondering if its still worth buying this iPhone 4 since the new 4s will hit shelves soon. also I'm currently on a contract and won't be able to upgrade till this month next year. i just want to know if ill be missing out on something if i purchase and this iPhone. thanks. ps. i know the new one has the voice assistant but i don't mind not having that feature.
