Hello, long time reader first time poster. Quick question about verizon's latest ****** policy, one that we all know quite well by now....the death of the unlimited data grandfathers. Background: Long story short, about a year ago I got really bored with the iphone and the lack of any major changes to the UI and the little screen (so much bezel...why??) So i owned a few androids, now I have a galaxy nexus and it just hit me...Im tired of owning a buggy phone that works 50% of the time, I want my iphone back. So im coming back home, adios google. Now for the question: I really really want to keep my unlimited data for as long as I can. I know that upgrading (my contract isnt up until Feb '13 anyway) will instantly void and override my current unlimited data. This means that I will be buying devices outright on ebay for quite some time. Im ok with that. But if I were to buy a used 4 or 4s, would this affect my current data plan since it would mean going from a 4g to 3g device? I know it isnt sold as a 3g or 4g data plan is it, its just a data plan? And if not, when the iphone 5 comes out with 4g capability, would I run into a similar problem again? I really think I'd be in the clear but I know verizon and that they'll try to catch me any way they can. Any info would be greatly appreciated! I am eager to ditch this plastic junk for something that is reliable once again.
