They say that, but in practicality I now have coverage with VZW in a number of spots where I had no Sprint coverage even when I forced digital roaming.
ditto. my sprint treo 755p doesn't work in the house (1/2 bar, phone would ring but never hold a call) and when my bil comes over his crappy $40 verizon phone gets 4 bars.
outside the house, can't really tell. the coverage map for spring show it barely covers my house, verizon easily covers my house location.
not enough of a bother to switch and the prl trick wasn't' something i wanted to mess with since 1/2-2/3 of my data always shows as roaming.
