The supported firmware versions will be:
iPhone4S: 5.0 (9A334), 5.0.1 (9A405) and the “other” 5.0.1 (9A406)
iPad2: 5.0.1 (9A405)
iPhone4S owners looking to maximize their chances of achieving an eventual software-based carrier unlock should be staying at 5.0. Everyone else should be at 5.0.1. If you’re an iPhone4S owner who already updated to 5.0.1, it’s too late to go back down to 5.0, but if you’re on 9A406 it is possible to downgrade the BB by going to the 9A405 version of 5.0.1 while the window is still open.

這個情況是不是他們還沒時間測試9A406到底jb後，長時間使用會不會有問題?
以上 有人解惑嗎?
還是賭一下 jb出了 ios 5.1 還沒出 ?
