The iPhone hacker behind sn0wbreeze, f0recast and BlackBreeze today has posted a tweet via his twitter account in which he has confirmed to have grabbed the decryption keys for iPhone OS 4.0. While the OS hasn’t been jailbroken yet, but according to iH8sn0w, it is very much possible.

An independent French developer has come up with another tool to fix all iTunes 9.1 problems on blackra1n’d iPhones running iPhone 3.1.2 firmware. This tool, like BlackBreeze promises to fix all issues that you may be having with iTunes 9.1 and your iPhone, running on jailbroken iPhone 3.1.2.

iTunes 9.1, which was released a few hours ago caused syncing issues for many users (specially on Windows), who were jailbroken on iPhone 3.1.2 (tethered) using blackra1n. But now thanks to ih8sn0w, this issue can now be fixed by using BlackBreeze.
