Haven’t seen much from the iPhone Dev Team lately but they released an update to their ultrasn0w product that fixes an issue for those running firmware 3.1.x with the 04.26 baseband. Apparently, that specific combination resulted in a missing carrier name in the upper left hand corner of your home screen (Springboard).

Ultrasn0w update from 0.91 to 0.92 fixes that problem, which was important for roaming on your iPhone. You should see that update live now if you have http://repo666.ultrasn0w.com as a Cydia source. If not and you want/need this update then you should definitely add it by going to Cydia -> Manage -> Sources -> Edit -> Add and input the above URL.

The iPhone Dev Team released an update to ultrasn0w (Version 0.9) and the update fixed a majority of problems seen by ultrasn0w users but you may still see a few problems here and there…

Problems you may see include:

• 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.

The iPhone Dev Team has pushed out a great update for their IPhone 3G and 3GS unlocking tool, ultrasn0w. This update fixes a bunch of little bugs here and there.

Features:

• Works on both 3G and 3GS
• Works on hacktivated devices
• Works regardless of how you jailbroke your device
• Doesn’t patch any mach-o binary whatsoever. (Doesn’t require a separate patch as each new firmware comes out).
• Doesn’t install any additional daemon
• Has no race conditions, no popups about “Missing SIM”, no network issues
• Is almost 7000 times smaller than its nearest competition :)
• Is available now via Cydia. Source repo is http://repo666.ultrasn0w.com (that’s ultrasn0w with a zero!)

If you haven’t yet updated to ultrasn0w 0.9 then we highly suggest you do! So fire up cydia and update that puppy!

Yep, The iPhone Dev Team have done it again! They have successfully unlocked and jailbroken the iPhone 3G S. But, unfortunately, they do not have an announced release date but will most likely be released after iPhone OS 3.1 is released by Apple.

From iPhone Dev Team’s blog:

Our ultrasn0w program uses the at+xlog crash as an injection vector of our unlocking payload — and it does so on the 3GS in exactly the same way as on the 3G! But this injection vector will be lost if you update to 3.1 using the official Apple IPSW, which updates the baseband. So stay away from official 3.1 IPSWs until we release the tools that let you update the firmware without updating the baseband.

The iPhone Dev Team urge you not to update to iPhone OS 3.1 if you want to be able to unlock your iPhone 3G S. You have been warned!

Well, I know many of you have been waiting for this news, so here it is: iPhone Dev Team has found out that 24kpwn, the same exploit used to crack open into the iPod Touch 2G, lives in the iPhone 3GS bootrom. That means the iPhone Dev Team can apply the same technique that they use to jailbreak and unlock on their current redsn0w tools. The baseband is also exploitable with ultrasn0w. Awesome news, ey?

From iPhone Dev Team:

Important: Apple has not given up on the cat&mouse game, and in fact there are challenging aspects of the 3GS jailbreak that aren’t in the other devices. It’ll take some time to work these into our tools, but the fundamental weaknesses are there: The bootrom is exploitable via 24Kpwn, and the baseband is exploitable via ultrasn0w. (And just like with the 3G, ultrasn0w for 3GS requires that you not update your baseband when Apple comes out with new firmware.)

If you would like to know the technical notes, from the iPhone Dev Team, on where the 24Kpwn exploit is in the 3GS visit here

Now it’s time to wait for the iPhone Dev Team develop and release the tools for users to use and jailbreak and/or unlock their iPhone 3GS’
