Hello, I 'm new here. I registered because i thought this would be a place to count for a reliable answer. I 'm in Bangladesh and i have bought an iPhone 4s 64GB off someone. I checked the model number on the internet later and it turned out to be from Sprint. It is unlocked and accepts all GSM operator SIM cards. So far it 's all good and unlocked. I have flashed and restored the firmware numerous times to see if it gets locked or if there are any issues with the activation process. It passed with flying results. Now, i have read plenty of articles and done tons of research about Sprint 's statement on locking 4Ss bought and activated after 11/11/11. I understand the point about buying it before or after 11/11/11, but the activation process occurs everytime you restore the firmware. So, my question is, will there be a moment in the future when i will end up with a locked phone after a firmware restore and get stuck at activation? I have restored 5.0.1 couple of times this month (which definitely means after 11/11/11) and it didn 't get locked. It 'll take the weight of this world down from my heart if someone is kind enough to answer the question.
