Sn0wBreeze 2.9.5 supports unteathered IOS 5.1 Jailbreak for iPhone 4 (GSM)

Sn0wBreeze has been updated to support an unteathered 5.1 (and 5.1.1) jailbreak on the GSM iPhone 4 and 3GS.  iPhone 4S users will need to use RedSn0w.

It also contains a fix for 3GS users using the 6.15.00 baseband having trouble with location services.  So, if you've switched to the iPad baseband and are encountering issues with your GPS, download Sn0wBreeze and watch the problem disappear :-)

Absinthe 2.0 provides unteathered IOS 5.1 Jailbreak

Great news on the Jailbreak front - after nearly 3 months of waiting, we finally have a working unteathered IOS 5.1 (and 5.1.1) Jailbreak for all iPhone, iPad, and iPod devices via Absinthe 2.0.  The only non-working device is the Apple TV.

Expect new versions of RedSn0w and Sn0wbreeze to be released within a few days.

IOS 5.1 Unteathered Jailbreak Status

There's still no working unteathered Jailbreak for IOS 5.1, but a new exploit discovered yesterday makes it possible to downgrade to 5.0 (SHSH blobs required).  This is great news for the many people who mistakingly upgraded to 5.1 assuming a jailbreak would be released soon.

Here's a table with the current supported jailbreak status.

	4.0.1	4.1.0	4.2.1	4.2.8	4.3.2	4.3.3	4.3.5	5.0.1	5.1
iPhone 3G	U	U	U	N/A	U	U	U	U	U
iPhone 3GS (old bootrom)	U	U	U	U	U	U	U	U	U
iPhone 3GS (new bootrom)	U	U	U	U	U	U	U	U	T
IPhone 4 (GSM)	U	U	U	N/A	U	U	U	U	T
IPhone 4 (CDMA)	N/A	N/A	N/A	U	U	N/A	N/A	U	T
IPhone 4S	N/A	N/A	N/A	N/A	U	N/A	N/A	U	N
IPad 1								U	T
IPad 2								U	N
Ipad 3	N/A	N/A	N/A	N/A	N/A	N/A	N/A	N/A	N

IOS 5.1.1 released

IOS 5.1.1 is now out to fix some reliability and security bugs in IOS 5.1.  The good news is you can upgrade to 5.1.1 safely, the re-jailbreak on 5.1.  The bad news is the jailbreak for 5.1 is still teathered, unless you have an older bootrom iPhone 3GS.

AT&T's Easter Present - Free iPhone Unlocking

Great news for AT&T customers wanting to unlock their iPhones.  Starting today, the company will give you a free IMEI unlock code straight from Apple.  This will work regardless of baseband, with no Jailbreak or SIM adapter required.

But there's one big catch to qualify - you have to be a current AT&T customer with a completed contract.  For example, you originally bought an iPhone 3GS in 2009 and upgraded to the 4 or 4S on your own without renewing your contract.


The move makes business sense for AT&T.  With the 5-year deal signed with Apple expiring soon, the company is looking to differentiate itself from competitors.  Even though Verizon and Sprint carry the iPhone 4S, both still lock it to their network and charge roaming fees when travelling abroad.  Additionally, the iPhone does not support T-Mobile's 3G network, making it unlikely that unlocked customers will leave for that competitor.

Baseband 4.11.08 downgrade via Chinese SHSH server?

In the latest chapter of iPhone baseband 4.11.08 unlocking, Chinese Hackers have claimed to have created a SHSH server capable of letting users downgrade their IOS and thus also downgrade to the unlocked 4.10.01 baseband.

Will it work?  Hard to say.  Setting up the server is the easy part, since TinyUmbrella has been doing this for years.   The real trick will be creating fake SHSH blobs, which would require cracking Apple's code.

I'm very skeptical that this will be a working solution.  If cracking Apple's SHSH codes were so easy, it would have happened a while ago.

New iPad doubles as hot plate?

Last week, a co-worker pointed out that the A5X CPU on the new iPad was 10% larger than its counterpart on the iPad 2, however still uses the same 45 nm architecture as the iPad 2.

This raises a question - is the new iPad prone to turning uncomfortably warm or overheating?  Looks like the answer may be yes.  According to multiple sources, when holding the iPad upright, it gets warm in the lower left corner:

Naturally there have been some "iPad Fire" jokes.  Ha, ha, ha. While this may remind many of the iPhone 4 antenna fiasco, keep in mind back in 2009 there were reports of the iPhone 3GS overheating that turned out to be unsubstantiated. So, we'll see.
