Carrier contracts and device subsidy policies mean wireless subscribers who want the latest and greatest iPhone have to think carefully about their upgrade strategies.
In this edition of Ask Maggie, I offer some advice to one frustrated reader who has been waiting a long time to upgrade to a new iPhone. She can't decide if she should pull the trigger now and buy the iPhone 4S, or whether she should wait for the next upgrade to the iPhone, expected next year.
I also explain how the fact that Apple has used common chips for the iPhone 4S on AT&T, Verizon Wireless, and Sprint Nextel means that travelers have more freedom to use their phones when they're overseas. But at the same time, the software each carrier uses to lock these phones to their own networks, also limits where and how they can be used.
