Motorola V265 / V266 / V276

The first day I had the phone I noticed that the Accuweather app had both a subscription for 2.99 and an unlimited option for 5.99. When you choose the unlimited option, does that mean that the app can be used anytime with only airtime being used? The next question is, I didn't choose either one, and now when I go into the GetItNow screen and the unlimited option is not there. Is there a way to get it back? or do those things change consitantly?

Thanks,
Ryan
