I have 4 months left under my two year contract with Verizon. I also have an unlimited plan. Seeing as I really don't understand how cell phone companies work, I'd rally appreciate some help! I want to upgrade to an iPhone 5 and keep my unlimited plan. I understand to do this, I need to buy the phone outright (something like $750). But do I need to wait until the 4 months of my contract are up, or can I go ahead and buy the iPhone 5 and activate it and do whatever with the iPhone 4 I currently have? Thanks for any help, I'm a big newb to iPhone!
