I left my iPhone because I hated whenever I dialed and got an immediate call failure. It wouldn't even attempt to dial out. Now I have my Evo, and it dials out all the time, but about 5% of the time, I don't hear the ringing or the other end. I've had it happen where the person on the other line is frustrated with me because they think I'm prank calling to them. Has this happened to anyone else? Dial out but nothing in the ear piece? If so, did you find a fix?
