I am planning to take my iPhone 4S on Verizon to Taiwan in a couple of weeks. I have a couple of questions. The last time I went to Taiwan, I brought the iPhone 4 on Verizon with me. I could not get data, only voice, because the CDMA network there only supported voice. Now that the 4S has GSM bands inside, when I land, will the phone automatically go to GSM or do I need to to switch a setting? If I need to switch a setting, where is that setting located? When I am in Taiwan on GSM mode, will there be a Carrier Menu so I can switch between the differnt GSM carreirs that verizon has agreements with? Also, where in the States, by the signal bars you would see Verizon, what will be displayed there? Would it say "Roaming" and the Carriers name? Thanks!
