Hey, I updated iPhone 4 to 4.2.1 and JB with greenpois0n, one of the first apps I installed from cydia is my BiteSMS and it worked fine for quite awhile. As I've added things on cydia all the sudden I couldn't call or text out (call failed or message send failure as well as not being able to receive calls/texts). I removed biteSMS, rebooted and it worked fine. I've tried reinstalling biteSMS and I get the same issue. I've rebooted after install and after I have the issue and then it'll work for a text or two then goes back to same issue. As soon as I remove BiteSMS, it works fine. Any fixs! Any ideas? I thought it was cuz it wasn't updated for 4.2.1 but I just saw somebody else on iphone4, 4.2.1, GP JB is using it with no issues.
