So lately I've been kind of partial to a non-JB'd iOS, but I have somewhat of a good reason to jailbreak - I sometimes get calls from people I don't even know. Is Ac1dSn0w real? Will it untether jailbreak my iPhone 4S?
Once again, there is no jailbreak at all for the iPhone 4S running iOS 5.1. Bootlace is only for installing OpeniBoot on the iPhone 2G, iPhone 3G, and iPod Touch 1G. It does not untether a jailbreak, nor alter the jailbreak.
