slmclarengt, i have the EXACT same issue that you do. It can't be the service because it shows that I have full bars and I still don't receive my text messages on time or phone calls. I had a regular HTC touch and went to the sprint store because of this problem, then they sent me a replacement...same problem. So i sold my touch and bought a diamond and yet again...same problem. I've given up hope as I have talked to sprint tech support countless time and the problem still persists. Oh well, i guess i'll have to wait until the Pre.
