I'm having trouble finding answers that suit my question, so I figured I'd ask here. My mom's iPhone (4s) is out of warranty and the power button now gets stuck. While I don't see it as a problem to just leave it on, she does. While my mom could just wait a week and upgrade when the cycle restarts, I was just curious if anyone knows about verizon and how they handle upgrades during a cycle? Currently she's grandfathered on unlimited, so she'd have to switch to a tiered data plan should she take the contract price. How does the data charges work in this case since the phone's plan will be changed? I know this isn't a verizon forum, but I thought maybe some members might have experience with this situation.
