I'm pretty sure I know the answer to this but is there anyway to change the pattern of the vibration just for SMS notifications? Right now it has the same pattern as an email and I can't tell them apart. I know I can download Handcent and it will do it but I don't want to lose the emergency alerts, even though they function sporadically. I don't really have a complaint with the factory messaging app beyond this and it seems like this would be something fairly easy to change.
