Ultrasn0w was updated to support old baseband on new iOS 4.3.3.
Here is the list of supported basebands:
Ultrasn0w 1.2.3 (for unlockers with old baseband) is available in Cydia.
You can update to iOS 4.3.3 and preserve old baseband using two utilities. Here are step-by-step instructions:
PwnageTool 4.3.3.1 (Mac OS)
Sn0wBreeze 2.7.3 (Windows)
The iPhone Dev-Team released an update to UltraSn0w that makes it compatible with iOS 4.3.1 for basebands previously unlocked. You can use ultrasn0w if you need carrier unlock and you have compatible baseband, preserved with pwnagetool, sn0wbreeze or tinyumbrella.
Ultrasn0w 1.2.1 supports only the following basebands:
You can install ultrasn0w via Cydia.
Here are DevTeam comments:
DevTeam released much anticipated untethered jailbreak for the latest iOS 4.3.1 – RedSn0w 0.9.6 rc9 and PwngeTool 4.3.
The 4.3.1 untether works on all Apple devices that support 4.3.1 except for the iPad2:
Redsnow is easy to use, it is available for Windows and Mac OS. Pwnagetool can be used to create custom ipsw and preserve baseband, it supports Mac OS only.
You can download RedSn0w 0.9.6 rc9 here and PwnageTool 4.3 here.
Here are our tutorials:
Ultrasn0w doesn’t work on iOS 4.3.1 yet (even with iOS 4.3.1 + old baseband). The fix will be available soon. Here’s a warning from DevTeam for unlockers:
Here’s what hackers tweeted about new Apple firmwares 4.0.1 for iPhones and 3.1.2 for iPad:
DevTeam:
As with *any* new FW, jailbreakers + unlockers must avoid this upcoming 4.1 update until our tools are updated
3GS, ipt3G, iPhone4 users (regardless of current FW or JB status) should backup 4..0 SHSH blobs http://is.gd/dskh9 soon
Obviously avoid today’s 4.0.1 update until JB tools are updated. Luckily, no baseband change so ultrasn0w lives on
each FW version has unique blobs. But using http://is.gd/dskh9 you can get 4.0 blobs on PC while you stay at 3.1.2
Hah for those iPhone3G or ipt2g(non-MC) users at 4.1beta1: use redsn0w from 2 wks ago to JB http://is.gd/dstU3
Comex:
3.2.1 and 4.0.1 out. if you want an unlock, DO NOT UPDATE. No, the jailbreak is not ready yet.by the way, there is absolutely no reason to update to 4.0.1. it only improves the formula for _displaying bars_, not actual signal
Planetbeing:
There’s no baseband update, so signal strength or radio performance cannot have improved.Hey guys, I recommend any iPhone 4 users who need jailbreak or unlock use http://3.ly/zN58 to back up their SHSHs NOW, and not upgrade.
iH8sn0w:
WARNING: 3.2.1 for the iPad is out. It KiLLS the Spirit Exploit. 4.0.1 is out too (not for the iPad though)
Good news from DevTeam. They just announced via twitter that unlock for firmwares 3.1.3 and 4.0 is ready:
RT @MuscleNerd: ultrasn0w tips: 1) Works for all basebands since 3.0 FW 2) Remember to disable 3G on T-Mobile USA
ultrasn0w 0.93 released! Cydia repo is repo666.ultrasn0w.com. Works with basebands 04.26.08 thru 05.13.04
This means, that all users with basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04 can use ultrasn0w 0.93.
There is no jailbreak for just released iOS4, so you need to wait a bit. Firmware 3.1.3 who need unlock can update ultrasn0w and use their iPhones with any carrier.
