My company asked me to turn in my blackberry and switch to an iPhone... Yay! Except I already have a personal iPhone, so asked them not to carry 2 of them around, they offered to switch my number and phone to their account (and they will release it back to me if I leave). According to our plan administrator, she said: "Your contract length and upgrade eligibility move with you number. Whatever your standing is on your personal account will be the same when it moves to the company account. Whatever old plans that you have on your personal account will move with your number also. They would only change if the line were to cancel." For those who have moved their phone from one account to another, has this been your experience? I mainly want to make sure the unlimited data plan stays with the phone.
