Is it possible to unlock iPhone 4 basebands 4.11.08 or 4.12.01? I have read that developers are no longer working on a software unlock for these versions. Is this true and why?

Software unlocks for the iPhone 4 on basebands 4.11.08 and 4.12.01 were never released by the jailbreak community. While the SAM exploit briefly allowed for an activation ticket backup method, Apple patched this quickly. For these specific basebands, the only reliable way to unlock the device is through an official carrier unlock. Most developers shifted focus to newer devices and exploits as Apple security became more robust, making a software-based exploit for older basebands a low priority.

These basebands are not unlockable via software. There was previously a method using SAM, but it was patched by Apple.
