Despite there are tools already available to jailbreak (tethered) iOS 5.0.1, MuscleNerd still warned jailbreakers and unlockers to stay away from iOS 5.0.1 otherwise there’s no way to downgrade to iOS 5.0.
MuscleNerd twitted earlier today:
“Jailbreakers and unlockers should avoid today’s 5.0.1 until a flow for downgrading to 5.0 is developed.”
Apple is doing all they can to avoid iPhone users to downgrade their device to early versions of iOS. Even if you have saved your SHSH before, potentially you won’t be able to restore to any earlier iOS version at all. MuscleNerd wrote about this on their blog a few weeks ago when iOS 5 was still in beta stage. In one of the paragraphs MuscleNerd specifically mentioned:
“Starting with the iOS5 beta, the role of the “APTicket” is changing — it’s being used much like the “BBTicket” has always been used. The LLB and iBoot stages of the boot sequence are being refined to depend on the authenticity of the APTicket, which is uniquely generated at each and every restore (in other words, it doesn’t depend merely on your ECID and firmware version…it changes every time you restore, based partly on a random number). This APTicket authentication will happen at every boot, not just at restore time. Because only Apple has the crypto keys to properly sign the per-restore APTicket, replayed APTickets are useless.”
A new advanced proximity sensor built into the iPhone 4S is not simply a proximity sensor, it’s Siri’s “eyes” to detect whenever you’re close to your iPhone 4S.
If you own an iPhone 4S you will be pleased to know that it has a cutting edge hardware. You might have already noticed a “raise to speak” feature on your iOS 5.
This allows Siri to be activated whenever an active iPhone is raised to the user’s ear or face. It is able to sense the raising action using a proximity sensor capable of detecting how close the user’s face is to the screen.
In a video featured on iFixit.com, it shows how the proximity sensor emits infrared light at all times to support Siri’s ‘Raise to Speak’ feature.
They also demonstrated how the iPhone 4′s proximity sensor is only activated while on a phone call, while the sensor on the iPhone 4S is active whenever the device’s display is on. You can watch the video below.
Well, that’s another reason why the iPhone 4S is light years ahead compared to other smartphones out there. Do you own an iPhone 4S already?
The home button on your Phone is the single most used button on the device so if it doesn’t respond well to your click, it gets really annoying and frustrating. Here’s a simple calibration fix that you can try.
You may want to check on your iOS settings if you accidentally enabled the triple-click Home function.
Simply go to Settings -> General -> Accessibility and make sure Triple-click Home is off.
1. Launch any app
2. Press and hold the sleep/wake (power) button until the slide to power off swipe bar appears.
3. Release sleep/wake button
4. Press and hold Home button lightly until screen returns to home screen. Done!
I posted this method about 2 months ago and it worked for most people.
OK, this may sound like a strange blog topic, right? Well, we’ve been trying to develop an unlock prototype for iPhone 3G and 3GS for all basebands without the need to jailbreak and use ultrasn0w. We have a video to prove it.
The video above shows an iPhone 3GS, model number MB715 (old bootrom) purchased from Apple Store with AT&T contract, unlocked to China Mobile network. This phone has baseband 5.13.04 that can be unlocked with ultrasn0w but I intentionally removed ultrasn0w to show that this method works.
I’ll try to find a 3GS with baseband 5.14.02, 5.15.04 or 5.16.02 and make the same video, hopefully over the next few days. Unfortunately this unlock doesn’t work on baseband 5.16.05 that comes with iOS 5.
If you don’t wish to update to baseband 6.15.00 to unlock your iPhone, this is your ultimate and safest solution. It will not affect your GPS and other risks associated with baseband 6.15.00.
