I'm pasting this from Verizon Infocenter. Don't have a RAZR myself but thought it might help some that do that might be having these difficulties...

workaround has been suggested due to end-users reporting connection difficulties
to the Verizon Wireless data network with their device. In order to resolve this
issue, the end-user should select "do not automatically turn on Wi-Fi" when
prompted which will allow them to connect to the VZW data network. Please ensure
that this option is not enabled as this may prevent VZW data connectivity.
just thought i'd share
