Yeah, I need voice and data. And primarily need it when I'm away from the office.You require voice+Data right? I also contended with this issue in my mind tremendously. However I Came to the conclusion that I will just use google voice to disable the iphone and forward all calls to my work desk phone, which I have softphone setup on my laptop which I can then answer with headset! I'll just switch the google voice settings over when I get off work to forward back to the iphone.
