I forget where I read it, but it wasnt my idea/discovery, but it is a great one. Download the full trial of bitesms 5 that just came out. Then get yourself a little app called firewall ip. Open bitesms and whenever a FWIP popup comes onscreen, select "global deny". Basically denying the access of ads that would show up in the free version. The only thing is that the small bottom bar stay saying something like "want to ge rid of this? Buy it". But that doesn't bother me at all. I want the app mostly for the ability to send and respond from the lockscreen.
