I liked this app but found it was the culprit for my losing data connection on CM7. I contacted the dev to report the problem, and this is the response I got: "You use an unstable, rare rom and then have the audacity to blame the app for loosing your data connection? The app has nothing to do with data. It only restarts the RADIO. Cm is broken, and I won't be providing support for experimental roms. Flash another radio or a better rom, and stop giving my app bad reviews, it a great app. If it doesn't work, it you that's doing something wrong." So, can anybody suggest another call blocking app?
