AT&T is continuing to do what it can to make sure it keeps as many iPhone customers as possible.

[ad#Google Adsense 300×250 in story]The latest incentive for iPhone customers is 1000 free rollover minutes for loyal iPhone users. Some users have reported receiving texts from AT&T offering them the minutes, according to 9to5mac.com.

There doesn’t seem to be any way to know if you’ll get a text or when it will come, but you can speed up the process. Apparently, if you text “Yes” to 11113020, you will get a response saying your account has been credited.

Seems to be a nice little bonus for customers that plan to stay with AT&T instead of moving to Verizon.
