I am a Dept of Defense employee that cannot have a camera phone at work.I have the 9650 non camera and have used BB phones for 10 years with excellent service.I would like to buy another nice phone with a camera and full screen for my off work hours.My BB phone has a full size sim.If I purchase a nice phone that can hold my BB sim can I swap phones between work and home on the same phone line.I am already paying through the teeth for the great vzn service and hate to change to AT&T for this option.Many of my coworkers have AT&T and swap sim cards and phones effortlessly.For what I pay for 3 lines with vzn I could SAVE $25 a month and have 4 lines from AT&T which solves my dilemma.But I do think vzn is the best service.I am a vzn stockholder too.Any info would be greatly appreciated.
