Hi, I have the iPhone 4 with Verizon wireless and my 2 year Contract ended sometime last year.. since then I have been paying the same rate on a month to month basis with unlimited data plan. I have wifi at work and at home.. in the last 6 months I have been trying to use my iP4 without wifi to see how much data I would use on any given month.. Here is the data: March 2013 - used 0.52 gb April 2013 - used 0.82 gb May 2013 - used 0.53 gb June 2013 - used 1.96 gb July 2013 - used 0.83 gb August 2013 - used 0.44 gb I don't know what happened in June... I just wanted to see what you guys would do.. I'm thinking with LTE I may use my phone a lot lot more which would result in more data usage.. Purchase the new iPhone 5S ( when it becomes available ) full price and keep the month to month service. Purchase the iPhone 5S at subsidized price and acquire a new 2 year contract and lose unlimited data plan. Thanks for your comments in advanced.
