We had reported last week that Blacksn0w, an extremely popular tool to unlock iPhone for iPhone OS 3.1.3 and iPhone OS 3.1.2 had been successfully ported to work with iPhone OS 4.0 Beta 4 and baseband 05.11.07.
Steve, the iPhone hacking expert who had released Blacksn0w RC2 for iPhone OS 3.1.3 has just released Blacksn0w RC2 for iOS 4.
This Blacksn0w port is based on modified binaries by msft.guy and the original Blacksn0w unlock released by Geohot.
Blacksn0w RC2 comes with the following release notes:
Use on Modem Firmware 05.11.07 ONLY!
V1.2: Support for 4.0 GM. Backwards compatible to 3.1.2/3 as well. V1.1: MyWi tethering fix
Geohot’s unlock for 3.1.2/3.1.3/4.0GM on the iPhone 3GS (and probably 3G). Please donate at http://blackra1n.com/ if you enjoy.
With 3.1.3 & 4.0 GM patch (when needed) by msft.guy. Packaged by Pushfix.info
This is an unofficial release but Geohot HAS given me permission to redistribute blacksn0w. All known issues with WiFi loss and boot loops seem to be fixed. If it doesn’t work for some reason, you should still get the SpringBoard. This allows you to uninstall if necessary. It is a little slower to boot because of the increased safety of the release. A 3GS boots to cell connection established in about 90 seconds in iOS 4 now (50% slower than 3.1.X).
Improvements may be made in the future.
As we had mentioned earlier, this is not the perfect unlocking solution for iPhone users as it can only unlock baseband 05.11.07 that was included in iPhone OS 3.1.2. So if you want to unlock iOS 4, you’ll need to preserve the baseband using tools like iPhone Dev team’s PwnageTool to update your iPhone with iOS 4 rather than upgrading via iTunes when it is released on June 21.
We would recommend you to wait for iPhone DevTeam to release tools to jailbreak and unlock iOS 4, which they’ve announced will be available shortly after iOS 4 is released.
