I have to make a decision soon as to what phone to choose with AT&T. They gave me a Blackberry but my contract is up and I am planning on upgrading. I am allowed to use my phone for work as I am house charge and I cover 4 wings. They txt me. and I have all my reference books on it. as well as things that I need to remember... will it make a differance if i am used to window type products. I have never used a Mac of any kind.
