Good day, dear friends! Want to buy iPhone 5S Verizon, but there is one problem. In our region only one operator and it works in networks of standard CDMA. We have a lot of people who bought a iPhone in the States, the operator connects them to your network, but there is one BUT. After connecting to update software on iPhone cannot otherwise fly off and network settings, your iPhone turns into an iPod. Have to wait until the new Jailbreak will be released to connect the device back to the network operator I want to explain to you this question. When connecting the operator makes the jailbreak and then the phone can work in my network, Also the phone is inserted in the SIM card of our operator. The question arises 1 Why the SIM card, if the settings still flash in iPhone. 2. Is it possible to unlock 5S Verizon for any operator (including CDMA). 3. Is it possible to do a copy SIM card Verizon using SIM reader? and change only certain settings for my operator And some information to leave to iPhone thought Verizon SIM card, but the phone would work in another CDMA network. I understand a little in firmware, want you to get me fixed, if something goes wrong. When connecting an operator programmable custom (sid, nid, a-key, etc.) in the modem (baseband) iPhone. Not difficult to guess that the jailbreak they need to access the modem, creating a virtual COM port (presumably) but the big operators are programming CDMA devices without jailbreak, then most likely there the cocoa is a device that is able to connect to the modem iPhone without jailbreaking in protected mode. Or maybe there is some service code that puts the iphone in the programming mode of the modem, through a secure channel. (as far as I understood, iOS data transfer is over a secure channel of SSH.) Because climbed in the file system using the program WINSCP. In General, why is there so much paperwork. Want to learn how to flash the modem and not be tied to the operator. Since I am not a supporter of Jailbreaking. I want to be able to update the software without consequences. As an OEM operators such as Boost Mobile or starts with the OEM Wireless operators CDMA under Verizon'om work. Maybe I do not wrote do not judge strictly iOS only recently started running. Basically the ANDROID device's programming.. Please help in this complex process as the firmware is SUPER protected operating system iOS
