Bought a 4S this past weekend on AT&T, have grandfathered unlimited plan, and have noticed the 4S unlimited plan is different than the 4 unlimited, they are listed separately on AT&T website when you upgrade as well. When I do *3282# to check my data it lists the old data plan as "deactivated" then lists the second unlimited data plan along with it's usage.
I'm curious if switching back and forth between the 4 and 4s via switching the sims could possibly cause any issue with the data plans, as I know when you switch from a dumb phone to a smart phone, AT&T auto detects and adds a plan for you.
I am switching back and forth because my Iphone 4 is jailbroken and thus has a lot of functionality that the 4S does not, most important for me sending/receiving Google Voice SMS via stock text messages app. I will eventually sell my 4 once I get past 4S return period, but for now need to know if sim swapping could mess up anything with unlimited data?
