Newbie question here. It is very important to me to get an audible notification for missed calls and SMSs. I guess Handcent takes care of the SMS issue for me, but missed calls are still an issue. Is there an app that works well for the Nexus S 4G? (Mine is not rooted; I'm still figuring out how to use it! ) There are a lot of apps out there, but reading the reviews makes me realize that each phone is different.
