Apparently Apple just made some changes to iTunes in which @musclenerd described in his Twitter as “personalized-installation-server-host and -port settings in preferences.”
“iTunes 10.2 finally honors personalized-installation-server-host and -port settings in preferences. But I wonder why now?”
In other words that means you can now get your SHSH blobs from Saurik or TinyUmbrella server without having to change your host file.
To those who are new to jailbreaking, changing the host file will “trick” iTunes to check Saurik or TinyUmbrella server (instead of Apple server) for saved SHSH blobs so that you are “allowed” to downgrade your firmware. If you don’t change the host file, you will get an error message when you’re trying to downgrade to an earlier firmware.
Of course, no one knows why Apple made this change. Maybe Apple has a new trick up their sleeve?
Download iTunes 10.2 for Windows or Mac.
One of readers has suggested a possible workaround to make the GPS on your iPhone 3G or 3GS work again after upgrading your iPhone to baseband version 6.15.00. Currently we are still waiting for the baseband fix from the iPhone Dev Team.
This workaround will also work on other apps that rely on your GPS, such as TomTom GPS and it gives up to 1m (3 feet+) accuracy on pin-pointing your location. Not too bad!
What you need:
- Your iPhone has to be jailbroken (obviously – otherwise you won’t have baseband 6.15.00 :) )
- Bluetooth GPS logger device – either M-241 or 1200E is recommended
- BTstack app available via Cydia for US$5.00. The demo version does not send data to other apps.
Details of the workaround can be viewed on this YouTube video.
If you don’t like this solution, you can either wait until the fix is out or consider this.
Thank you Adrian for the tip.

Download iOS 4.3:
The last ‘Sunday is Fun Day’ we had was on November 28 last year when ultrasn0w 1.2 was released to unlock baseband 6.15.00 for iPhone 3G and 3GS. That unlock came out a few days after iOS 4.2.1 was available for download via iTunes.
Now that iOS 4.3 will be officially available by March 11, the iPhone Dev Team may release the new version of ultrasn0w (1.3?) shortly after that, assuming the unlock is already available. This is based on @musclenerd’s tweet that no unlock will be released before iOS 4.3 is out.
Another speculation is that @musclenerd may have discovered a way to unlock baseband 5.14.02 and 5.15.04 for iPhone 3G/3GS.
Let’s keep our fingers crossed and hope that March 13 or any day this month will be another ‘Fun Day’ for us! Be sure to subscribe to us and be the first to know once it’s out!
With the release of iOS 4.3 scheduled for Wednesday, March 2, Friday, March 11, the wisest thing you can do today is to save your iPhone iOS 4.2.1 SHSH blobs either on Cydia, or to your local hard drive with TinyUmbrella.
Saving your SHSH blobs will be extremely helpful if you ever want to downgrade your iPhone to previous firmware version. You will be so glad that you did it. Don’t worry, it’s dead simple.
If you have a jailbroken iPhone, Cydia can do this for you automatically. Launch Cydia and tap “Make my life easier, thanks!”
However, to give you 100% assurance, you can always use TinyUmbrella.
Follow the steps below:
Step 1: Download TinyUmbrella from here.
Step 2: Launch TinyUmbrella and plug in your iPhone. TinyUmbrella will automatically detect your iPhone and your current iOS version.
Step 3: Click “Save My SHSH”.
Step 4: That’s it! You should get a message saying your SHSH blobs were successfully saved both locally and on Saurik’s servers.
If you ever accidentally upgrade to a newer iOS, you can always downgrade to iOS 4.2.1.
Warning: Upgrading to iOS 4.3 will also upgrade your baseband/modem firmware to 5.16.00 (3GS) or 4.10.01 (iPhone 4). Currently there is no way to revert to your old baseband and there is no software unlock available!
