I use Sprint in the US but travel a lot to Europe. I have an Orange C500 (US equivalent is Audiovox SMT 5600) smartphone and love it. Only shortcoming for me is it is not quadband GSM (US model has 850/1800/1900) and Euro has 900/1800/1900). It is much smaller than the A700 and does just about everything. I will keep Sprint for the US, and am looking to upgrade my A460. Will the A700 do everything that my SMT5600/C500 does?
