Today I am the proud owner of a Verizon RAZR V3m. So far it works perfectly with iSync (for contacts and calendar) and gets good reception in my apartment. I haven't been able to get a good file transfer going, but there are some tricks to work around it that I'm trying. I've only been successful with sending myself a ring tone in a text message, but those will cost me $0.25 each, so I'm trying to figure out how to just do a regular transfer.
I have 15 days to play around with the phone and the service, and if I don't feel like there's a marked improvement in reception, then I may well go try something else. But so far I'm pretty content (and enjoying playing with my new toy!)
