If you have updated your iPhone 3G & 3GS baseband to 06.15.00 using Redsn0w 0.9.6b5 or using Pwnagetool 4.1.3, you can proceed to unlock iOS 4.2.1 on iPhone 3G and iPhone 3GS using Ultrasn0w 1.2 (the carried unlocking) by following the video tutorial made by iPhone Arena below:

Disclaimer: remember follow the entire instructions on the video by your own risk, I and the one inside the video will not responsible for any damage of your iDevice, good luck.

The iPhone Dev Team keeps their promise with the release of the unlock edition tool, namely PwnageTool 4.1.3 to unlock iPhone 3GS, iPhone 3G on baseband 05.14 or 05.15. Why this release is called unlock edition? Because this version is dedicated to those who are still locked on 05.14 or 05.15 baseband and desparately want to unlock their iOS devices with Ultrasn0w.

Since currently Ultrasn0w V1.2 unable to help you to unlock the iPhone 3GS, 3G on baseband: 05.14.XX or 05.15.XX thus, PwnageTool V.4.13 is needed to help you update your existing baseband to to 06.15.00 so you can continue unlocking the baseband using Ultrasn0w.

But unfortunately, PwnageTool for Mac OS only. For Windows platform fans, wait for the upcoming version of Redsn0w tool to be used to update your iPhone baseband to 06.15.00.

• Start itunes in recovery mode
• Restore and update it
• Now close the itunes
• Continue with Loading the Blackra1n RC3 to the desktop connect the iPhone with USB
• Now press make it ra1n with out pressing any button on the iphone

After few seconds u will see geohot and pop up on your desktop.. don’t touch anything and then a few more seconds latter it will reboot it self

Now your iPhone is jailbroken and the next phase is enter blackra1n icon and install sn0w.

Hope it will work for you too and see you in the next post!

For many times, George Hotz or his famous name Geohot has proven he knows what he’s doing and has helped many iPhone users in Jailbreaking or Unlocking their iPhone using his amazing tools such as Blackra1n, and now he comes out with Blackra1n to unlock iPhone on 05.11.07 baseband, so in other word, whatever carrier your iPhone uses you can unlock iPhone 3.1.2 (iPhone 3G or iPhone 3GS), because Blackra1n Unlocks iPhone for All Carriers!

And here is the video tutorial to Unlock iPhone on 05.11.07 baseband with blacksn0w:

But firstly you need to download Blackra1n RC3 To Unlock And Jailbreak iPhone 3G, 3GS 3.1.2

If you have unlocked your iPhone 3G or iPhone 3GS using ultrasn0w, but having troubles afterward, men behind iPhone Dev-Team have listed solutions for your unlocked iPhone using firmware 3.0 in Ultratips, here are the troubles you are probably having now with their solutions:

• Unusual battery depletion is almost always caused by people choosing to “Restore from backup” instead of “Setup as new iPhone” when iTunes asks you.  This isn’t caused by either the jailbreak or the unlock, but it’s a common 3.0 snafu. The fix is to just re-run the official 3.0 restore and choose “Setup as new” this time.  Your music and apps and all that will still be synced, but you’ll get rid of any conflicting wifi, bluetooth, or carrier settings.  Then just re-run redsn0w and install ultrasn0w.
• Remember, ultrasn0w works with hacktivated phones too, but don’t outsmart redsn0w into thinking you don’t need hacktivation! If you don’t plan on using an official sim, don’t activate via iTunes with such a sim.  Just keep your unofficial sim at all times and let redsn0w and ultrasn0w handle hacktivation
• T-Mobile in the USA doesn’t use the 3G frequencies that the iPhones support, so turn off 3G in Settings->General->Network.  (Some T-Mobile territories gracefully hand down to Edge mode, but most do not).
• Certain unofficial plans have limitations on whether you can make calls and use data at the same time. That’s not unlock-related.
• Some people have installed previous versions of ultrasn0w using non-standard techniques. While the ultrasn0w 0.9 update should have removed all previous versions of ultrasn0w, these users may have outsmarted our removal.  So make sure you don’t still see /usr/bin/ultrasn0w present if you’re at ultrasn0w 0.9 (which doesn’t have such a binary anymore).
• If you don’t need or plan to update to ultrasn0w 0.9 from a previous version, you can avoid having that red badge over Cydia by removing repo666 as a Cydia source.  Don’t worry, you can always add it back later  If you follow us on twitter you’ll be advised of any new updates anyway.

But Dev-Team has not added the solution to fix for Push Notification System on the jailbroken iPhone’s, but who knows they may come with ones in the near future, just wait and see. Therefore keep in touch with SEO Blog & Technology to receive the next news.
