Previously, the highest number of free minutes Apple and AT&T had to offer was 1350 minutes. That's almost 23 hours; almost a full day. If you spend more time than that on the phone, you'll probably like this new offer for the iPhone (assuming you already have one). Apple now has an unlimited calling plan for iPhone owners.

The monthly plan is US$ 119.99 for an unlimited calling plan, with the usual 200 free text messages. Not a bad deal if you like to gab on the phone. You'd probably want to stick to your current plan if you don't use your iPhone for calls that much though.

Tough luck for those who've unlocked their units though: the unlimited calls plan is only available for AT&T subscribers. For more information on the call plan, follow the link below.
