iH8Sn0w has posted another teaser trailer for Sn0wBreeze, a windows utility to build custom iPhone ipsw files.
Another Teaser… I have no idea why Teaser 2 was removed. Anyway. Like always, its not done yet! GUI is subject to change. Like the window sizes 
Take a look below…
Here’s a new video preview of Sn0wbreeze, the iH8sn0w’s Windows tool that will be able to create a custom firmware, just as PwnageTool Mac.
In the video we see a preview of the graphic interface and the first functions. At startup we choose the expert or the simple mode and the rest should be exactly as we know it already.
With internet tethering enabled you can use iPhone internet connection on you desktop or notebook. Here is a quick tutorial for experienced users. For everybody else – just wait for the new version of PwnageTool or some other utility.
Here it is:
A bsdiff patch to apply to CommCenter in 3.1.2 to re-enable tethering is available and . It’s just a 2-byte patch as shown below (and an appropriate readjusting of the mach-o’s codesign hash):
USE THIS AT YOUR OWN RISK! Your carrier may end up charging you for unauthorized tethering access.
Update #1 It looks like a lot of people have been looking at CommCenter lately because IRC user CleanAir had a similar tethering patch. Meanwhile over in the 2G CommCenter, WhiteRat and geniusan for that platform. Kudos to CleanAir, WhiteRat, and geniusan for digging into CommCenter and coming up with patches!
Update #2 A few have started to pop up. Eventually this will be made a part of the normal PwnageTool flow but for now this is best left for the adventurous users out there!

bsdiff patches are the normal way that PwnageTool modifies Apple software. To apply one manually, you must first get the “bspatch” program. Then do:
bspatch CommCenter CommCenter-hacked CommCenter.patch
If you don’t have bsdiff but know how to use a hex editor, the differences are available in text format.
The correct SHA1 of the hacked file will be:
1b19712035f33654cf72838ebe1a2033931b56b2 # 3GS
063165c3fa3e21d30eb4b486fab924ba3ef0ea5e # 3G
You would then remove the original program and replace it. Don’t forget to ensure it has execute permission!
chmod +x /System/Library/PrivateFrameworks/CoreTelephony.framework/Support/CommCenter
After you’ve started using the hacked CommCenter, visit from your iPhone and install a new mobileconfig.

iH8sn0w has just released a new teaser video showing Sn0wbreeze, application for Windows that would basically be a clone of PwnageTool, equipped with the ability to create custom firmware and unlock the various devices.
Many users believe that Sn0wbreeze is just “fake,”.. Hopefully iH8sn0w did found an exploit and will finish Sn0wbreeze soon.
Let’s watch the video:
DevTeam just released PwnageTool 3.1.4. It allows users to jailbreak firmware 3.1.2 on iPhone 2G/3G/3GS and iPod Touch 1G/2G. It also supports OTB iPhone 3GS with firmware 3.1.x. We remind you that if you need unlock, do not update on regular 3.1.x firmware, use Pwnagetool to create custom firmware to preserve old baseband.
Here is a quick howto:
You can download PwnageTool 3.1.4 here.
There is only a MAC version of PwnageTool. DevTeam doesn’t plan to create Windows version.
