Blacksn0w Unlock Released for iPhone Firmware 3.1.3

Blacksn0w RC2 is now available for those looking to unlock their iPhones running firmware 3.1.3. Beware however, this will not work with the latest baseband version 05.12.07. If you've updated your iPhone to 3.1.3 using Apple's official firmware you are out of luck.

Those updating their jailbroken device to iPhone OS 3.1.3 using PwnageTool 3.1.5 have taken advantage of Apple's battery fixes without altering the baseband from its current unlockable version, 05.11.07. In this case you can now download blacksn0w RC2 from Cydia.

The new version of blacksn0w by msft.guy is said to correct Wi-Fi bugs as well as unlock the older baseband under firmware 3.1.3. GeoHot, the original developer of blacksn0w, has not commented on this release. The package will be available from the MMI repository, however if you must unlock your iPhone immediately just add the repository below:

In January, iPhone Dev-Team released PwnageTool 3.1.5 for Mac OS X. This tool preserves your 3.1.2 jailbreak and ultrasn0w unlock when upgrading to firmware 3.1.3. We're guessing if you are interested in running blacksn0w RC2 you were already jailbroken but never bothered to download ultrasn0w.

Unfortunately, as of yet there's no way to jailbreak your iPhone running 3.1.3 if you used the official Apple firmware or if you have a device with factory-installed 3.1.3 firmware.

There IS A WAY to JAILBREAK if you accidentally upgraded to 3GS to 3.1.3 with the official Apple Firmware. I have a 3GS. I accidentaly upgraded. All you have to do is to downgrade back to 3.1.2 & you're golden again! :) The steps are the same as downgrading from 3.1 to 3.0 (except that you should choose the OS appropriate files). I did have to repeat the process about 4-5 times which was frustrating, but now I'm back on 3.1.2 and jailbroken again :-)

I haven't tried unlocking though... maybe I'll give it a shot as well..

Jailbreaking 3.1.3 is not the problem, and downgrading to 3.1.2 is not necessary for JB. The problem is Unlocking with baseband 05.12.01.

Unlock for 3.1.3 baseband 05.12.01 will be released on June 7th 2010. Nothing can unlock that baseband on 3GS through software till then.

Anyone or any website who claims it can be unlocked is a scam or fake. Follow only.

is it available now? i'm on the ip[hpne 3gs 3.1.3 5.12.01 and i don't see an unlock.

Please tell me where to go to downgrade from 3.1.3 to 3.1.2 so i can jailbreak my iphone... let my cuzin upgrade it so i could get mms on my phone but i still dont have that so if u can help my i would love it im so stuck rite now... please help and rite back at
