I downloaded this app call handcent sms. It's a text messaging app that i want to use in place of the standard messaging app that is provided on the phone. Well anyways, I was wondering if the app requires internet connection even when im not near wifi. When i downloaded it, it said that the app requires full internet access, but it says that for every app that I have downloaded. I wanted to make sure because I dont have the unlimited data plan for it and i dont want it to make my bill extremely expensive. Please Help!!
