How to Downgrade iPhone iOS 5 Firmware to 4.3.3

Are you missing some key jailbreak tweaks now that you've updated your iPhone 4 or 3GS to iOS 5 firmware? Already tired of dealing with all of the shortcomings in iOS 5 notification center? Luckily if you have saved your SHSH blobs you can easily downgrade and return your iPhone to a jailbroken state (and reinstall LockInfo!)

SHSH blobs saved to Cydia

In order to downgrade you must have saved SHSH blobs. Pictured above are how saved SHSH files appear for each firmware version in Cydia, when they are saved to Saurik's server. Follow these steps to downgrade to earlier firmware, including iOS 4.3.3 for an untethered jailbreak with JailbreakMe.

5 Biggest iOS 5 Notification Center Failures

Let me start by saying that none of the items mentioned in this list are new discoveries. All of the gripes below could have been noted months ago, after Apple first introduced iOS 5. If not then, it could have been revealed by reading the numerous descriptions of Notification Center from IOS developers and other users that installed one of iOS 5's many beta versions. Instead, I plodded along ignorantly, happily enjoying the world of jailbroken notification handling (via programs such as LockInfo and Intelliscreen), assuming that when Apple released iOS 5, I'd have all the intuitive, useful goodness I'd been enjoying for so long built right in. Boy, was I wrong.

Apple seems to have taken a good idea and executed it surprisingly poorly. Concepts which seem as though they'd be simple common sense are simply ignored. Instead of feeling complete, the Notification Center implementation seems rushed, with obvious needs overlooked.

While there are other complaints, here are what I consider to be the 5 biggest oversights with the new iOS 5 Notification Center.

Video Shows Siri Working on iPhone 4

The mystery as to why Siri is exclusive to the iPhone 4S just got a little more interesting. 9to5Mac ported the voice command system from the iPhone 4S to the iPhone 4. In the video below, developer Steven Troughton-Smith demonstrates how Siri looks on the device.

9to5 claims it can recognize spoken commands and speak back to the user. The only problem is Apple's servers are not authenticating commands from the iPhone 4 hardware. Apple fans have been debating whether other iOS devices like the iPad 2 can handle Siri's AI. 9to5's discovery proves there are no technical reasons for Siri being exclusive to the iPhone 4S.

iPhone 4S Insurance and Warranty Plan Comparison

As savvy customers have learned that replacing a lost, stolen or broken iPhone at unsubsidized prices can run as high as $749, many customers choose to protect their investment with an iPhone insurance policy or extended warranty. In the past, we've warned our readers many times about buying overpriced iPhone insurance and extended warranty coverage from their wireless provider. The options offered by AT&T (AT&T Mobile Protect) and Verizon (Verizon Total Equipment Coverage), which are provided by a third party company named Asurion, were traditionally overpriced and offered poor value compared to independent iPhone insurance and warranty providers.

As the iPhone 4S arrives in customers hands today, we thought it was time for an update. For one thing, the information we provided previously is out of date. As independent providers such as Worth Avenue Group and SquareTrade have grown rapidly over the past few years, and as these companies have continued to receive excellent approval ratings from customers and consumer advocacy agencies such as the Better Business Bureau (BBB), the major providers have taken notice and made their coverage options more competitive. Apple has even gotten in on the game with their new AppleCare+, which adds accidental damage protection to existing AppleCare coverage.

iPhone 4S Surprises Not Mentioned in Apple's Keynote

Even though the iPhone 4S won't hit shelves for another day or two, several surprises have cropped up that Apple didn't mention at the keynote presentation. Some of these are great news for those in the market for an iPhone 4S. Other items that have slowly leaked out might not sound too optimistic but in the scheme of things there should be no major deal breakers for Apple.

Of course, many iOS 5 features continue to be discovered and Apple chose to discuss only highlights at the keynote, including the Siri personal assistant, iCloud and improvements to AirPlay. This is certainly the tip of the iceberg as Apple has included over 200 new features in iOS 5. So what did Apple keep to themselves about the iPhone 4S?
