My Treo blew up on me around 3 weeks ago and while getting a new cellphone I dumped sprint too.
I hated sprint because I live in the boonies and the signal was always weak and I dropped at least one in three calls sometimes two in three.
I bought the moto razor this time and switched to cingular. I love this phone and love the blue tooth set up more! I always have a strong signal now and as of today have not dropped a single call!
