I want add Handcent to my Incredible because I think the stock app is kinda boring. Works well enough, but boring. I read that a lot of people were getting notified twice of receiving messages if they didn't turn notifications off on the stock text messaging program. I have the 500 message plan (send most things by email) so here's my question. Will I get charged twice for each message I receive (even if I have notification turned off on the stock app) or just once? I'll be keeping a close eye on how many I've used each month, but this info would be helpful to know. Thanks!
