I'm trying to figure out if I can get an iPhone 5 at a subsidized price (my family's shared plan is out of contract) and then transfer that phone to my corporate plan (all AT&T). Here's the situation: Currently: Personal (shared minutes, only one line with data): iPhone 4S (micro SIM) Corporate: iPhone 4 (micro-SIM) Desired Scenario: Personal: Keep existing iPhone 4S Corporate: new iPhone 5 (possibly unlock existing iPhone 4 for another personal line, not sure yet) My corporate plan support says that they can associate a new SIM with my corporate account, but not a new phone. So could I do the following?: 1. Order iPhone 5 w/ 2-yr extension on Personal account data line 2. Call my corporate and have them associate the iPhone 5 nano-SIM with the corporate account. 3. Activate iPhone 5 on iTunes Would that work? Would AT&T force us to the new shared data plans upon upgrade? Also, would there be complications with the old iPhone 4 continuing to receive my iMessages or does iOS 6 change this behavior?: https://plus.google.com/u/0/11340187...ts/LL8qEp5nU4K Any help would be appreciated.
