I was not able to find any other posts that could answer my question. I just purchased an unlocked iphone with version 1.0.2. I want to get the most current version but I am using my iphone with T-Mobile. Will the anysim stay installed if I update to 1.1.1 and 1.1.2? I am not to worried about jailbreaking it. That seems pretty easy. I know how to pick which version I want to upgrade/downgrade in to itunes but I have not worked with the anysim install process.
