OK - here is my scenario:
I have a family plan with two iPhone 4's - Old plan, 1400 minutes shared, text feature, and unlimited data on both lines for $30/month. Both lines eligible for upgrade around 10/7. I use a fair amount of data, and would not mind keeping unlimited. My wife uses less than 1 GB/month usually. She also doesn't necessarily care about getting the iPhone 5.
My thought was:
1) Keep my old national access family plan with 2 lines.
2) Use the subsidy and upgrade to iPhone 5 on my wife's line, revert to 2GB $30 month data plan on that line.
3) Then switch the iPhone to my line, and reactivate her old iPhone 4 on her line. Or, sell both iPhone 4's and buy a 4S for her online or something.
Any reason that wouldn't work? That way, I would have unlimited data on the iPhone 5, and she would have 2 GB data on her phone.
I realize this will only work once, or at best, once every 2 years - ie, if I ever use a subsidy on my line, I lose my unlimited data.
Thoughts?
