A twitter post yesterday said it was ready for release already. I don't remember who it was from, I'll try and find it.
It is being reported by several Tech Blogs that Dev-Team (Comex) has successfully Jailbroken iOS 4.1 ahead of its rumored release on September 8th. The report was initially posted by a Tech Blog named ? Tracy & Matt ? mentioning:
? It is not even out yet, but the good people over at the iPhone Dev Team have managed to Jailbreak iOS 4.1. ?
This Jailbreak is achieved after Comex found two loopholes, who earlier released Jailbreakme.com a Web based user-land utethered Jailbreak for iOS 4.0 and 4.0.1. However we have yet to see the official confirmation either on Dev-Team Blog or the Twitter Accounts run by these Developers where they usually first post such information. We will of course keep you updated as more details become available.
