I own a iPhone 4 on Verizon. I currently have unlimited data. I can't upgrade until October and my contract ends like 2/13. Couple questions: 1. If I buy the iPhone 5 (4G device right?) at full retail price, will I then have unlimited 4G data or is this a problem because I have unlimited 3G? 2. After my contract ends on 2/13, will I still have unlimited data at month to month, or what happens?? Thanks guys.
