My launch day iPhone4 works fine. But, I am upgrade eligible. I am grandfathered in with unlimited data, and I am concerned that the next iPhone will not allow me to grandfathered (LTE). With that said, my usage is about 600 mb/month, with a peak of 1 gb. (I work in a spot where I can not carry the phone, so it is off, and at home I use WIFI). Furthermore, I have Verizon LTE on my new iPad, am impressed. So, I am thinking of waiting and not worrying about the grandfathered data plan. I assume the new iPhone will continue the good battery life, easily fit in my hand (no 4.5" screen), and be the same price. I do not know what new features. The reasons to upgrade now are: slightly better performance (2x CPU) Can get it in white (will be less likely to overheat while sitting in my car during the day) SIRI (maybe not) Known data plan Better camera If the iPhone 5 (or what ever) was not on the horizon, I would upgrade today. Any thoughts?
