iPhone Dev Team Releases Unlock For 3GS [Update: Comments From The Dev Team]

The iPhone Dev Team has released a new version of RedSn0w that jailbreaks the iPhone 3GS, as well as 2G, 3G, and iPod touch 2 on OS 3.0. It runs on both Windows and Mac, and has the same instructions for each as previous versions. The problems with Icy and Cydia have allegedly been resolved, and Ultrasn0w should work on the 3GS after you jailbreak with RedSn0w. Mobile Substrate and Winterboard are also now working on the 3GS. BigBoss is hosting the files here: Windows, Mac.

Update: The iPhone Dev Team has posted a statement on their blog explaining why they went ahead and released the jailbreak for the 3GS. Initially they wanted to wait until OS 3.1 was released to get as many people on board as possible before releasing it, as Apple would inevitably fix the hole in their next software update. However, this tactic became meaningless once purplera1n was released, as it uses the same hole.

As usual, the Dev Team had some reminders in the blog post as well:

ultrasn0w unlockers — You all must remain particularly vigilent against upgrading your basebands, since doing so will kill the unlock (for most phones, there’s no going backwards in baseband version). Apple has gotten very serious with the latest baseband — they’ve removed 180 (!) commands in an effort to cut down their exposure to holes. So please always stay away from stock Apple IPSWs and instead use our tools as we release them. These tools let you update your firmware without updating your baseband.

Those installing ultrasn0w will probably also need to do a single run of Settings->General->Reset->Reset Network Settings. We’re testing various fixes for that particular glitch.

redsn0w platforms — This is the first redsn0w release that also supports linux! It’s the newest version of the bunch, so any feedback would be appreciated. But right now, redsn0w should work on OS X, Windows, and linux.

How to get the goods:

The redsn0w torrent seeds are all here. Any direct mirroring help would also be appreciated.
The updates to ultrasn0w, MobileSubstrate, and WinterBoard are all handled directly through Cydia (after you’ve jailbroken!)
