Unofficial Blacksn0W Update Unlocks Ios 4 Gm Seed

An unofficial update to BlackSn0w has been released by Steve to unlock the iPhone 3GS (05.11.07) on pre-release iOS 4 GM firmware.

The update to Geohot's unlock is reportedly a little buggy; taking at least 90 seconds to pick up a carrier signal.

It is recommended that only advanced users take a look at this unlock until an official update is released by Geohot.

Here is the package description:

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.

The unlock can be found on the http://cydia.pushfix.info Cydia repository.
