iOS 4.1

Been holding out for redsn0w before jailbreaking your iOS 4.1 device. Good news: the Dev Ream has just released the latest version which will allow you to jailbreak your iPhone 4, 3GS, 3G, 3rd or 4th generation iPod Touch and second generation AppleTV on either Mac or Windows machines. It uses geohot’s limera1n exploit, and also adds “custom bootlogos for iPhone3G/iPhone3GS/iPod2G users (with qualifying bootroms)” and an option that implements the ‘DFU’ button in PwnageTool” in Windows.

Interested? Grab it here, and let the hacking commence.

Watch out! A major new security hole in the iPhone software has just been discovered… a bug that allows anyone who picks up your phone to easily unlock it and access all of your phone data under iOS 4.1.

In case you want to try it yourself, here’s how you gain access to a locked iPhone through the security hole. When your iPhone 4 is locked with a passcode, tap the emergency call button, then enter three hash keys. Now tap the call button then immediately hit the lock button.

Do the above correctly and you’ll be rewarded by being dumped into the iPhone’s Phone app. From there, you can access the user’s favorites, contacts, dial pad,. recent calls, voice mails and even send SMS and email messages through the Address book.

It’s a pretty huge bug, and it seems to work on all iPhones running iOS 4.1. This is the sort of thing Apple will patch pretty quickly, but in the meantime, show extra dilligence and care in not leaving your locked iPhone lying around.

Limera1n and greenpois0n have made it possible to jailbreak your iOS 4.1 device for almost a couple weeks now, but if you’re like me, any jailbreak not officially released by the iPhone Dev Team under the PwnageTool moniker is worth an eyebrow arch of circumspection.

Good news, then: the Dev Team have finally released PwnageTool 4.1 for Mac OS X, which used a combination of geohot’s contentious limera1n exploit, Comex’s PF kernetl exploit and the Dev Team’s own pwnage2 exploit.

It’s two days late, but late is better than never. GreenPois0n the jailbreak for iOS devices running iOS 4.1 is here. Unfortunately the first release is for Windows and Linux only, but the developers of the hack, Chronic-Dev, expect to release a version for Mac OS X soon.

The jailbreak supports iPhone 4, iPhone 3GS, the third and forth generation iPod touch, and the iPad. Although it doesn’t presently support the second generation Apple TV at this time a future update will fix that.

The release of GreenPois0n follows last weekends surprise release of Limera1n by Geohot. Afterwards, Geohot and Chronic-Dev got together, so GreenPois0n now uses the same exploit as Limera1n. This cooperation saved Chronic-Dev’s SHAtter exploit for a future jailbreaking tool.

As far as I’m concerned the hacker cooperation can continue. I appreciate what they do for people who want out of Apple’s walled garden and I hope they continue to work together on future iOS hacking tools.

One of the reasons owners of the iPhone 3G and iPhone 3GS have been waiting for a jailbreak for iOS 4.1 is to enable the iPhone 4’s impressive HDR functionality on their older handsets… a hack which is already available for jailbroken 3G and 3GS users on the iOS 4.1 beta through a Cydia app.

It looks pretty likely, though, that these users won’t need to jailbreak their devices to enable HDR functionality… Apple seemingly intends to add HDR in a software update coming down the line.

About a month ahead of America and Europe, New Zealand clocks fall an hour back when they switch to Daylight Savings Time on the last Sunday of September. Apparently, though, New Zealand iPads and iPhones are proving a tad overzealous when it comes to falling back this year: numerous iOS users are reporting that since yesterday’s switch, their alarms are going off an hour early. Given that Kiwis were already having to wake up an hour earlier than they were used to, that’s quite a rude awakening.

Are you the owner of an iPhone 3G who is disappointed that you can’t run deathmatch with friends through Apple’s new match making service, Game Center? A jailbreak and some hacking could get you up and running, if you’re feeling bold.

Over at Redmond Pie, Taimur Asad goes through the process of getting jailbreak running on an iPhone 3G… which is (coincidentally for this experiment) the only iPhone that can currently be jailbroken under iOS 4.1 right now.

It turns out we didn’t need to wait for the Dev Team to jailbreak iOS 4.1 after all: if you’ve got a jailbroken iPhone 3G or 3GS running the iOS 4.1 beta, all you need to do is download the HDR Camera Enabler through Cydia from the ModMy repository to enable high dynamic range snaps on your last-gen iPhone.

Presumably, this same tweak will also work with the Dev Team’s official iOS 4.1 jailbreak, which has yet to be released. Unfortunately, for right now, it’s 4.1 beta only, though, making it available to only a very small subset of jailbreakers. If you want to give it a shot, though, Redmondpie has a series of good tutorials on how to jailbreak the iOS 4.1 beta on the iPhone 3GS or iPhone 3G.

iOS 4.1’s ability to take high-dynamic range photos has been a much buzzed about new feature particularly to amateur photogs looking to maximize the quality of their casual smartphone snaps, but Apple does not appear to have gone it alone: according to some excellent research done by MacRumors’ Eric Slivka, it appears that Apple acquired a small, Cambridge-based company called Imsense to bring the feature to an iPhone near you.

Before being bought by Apple, Imsense did business in a technology called “eye-fidelity” which used software algorithms to remap image tons in order to produce nearly instantaneous Dynamic Range Correction in both standard and HDR photos. While the iOS 4.1 implementation of HDR is done in the classical fashion of blending three separate exposures into a single image, Imsense’s Eye-Fidelity algorithms appear to be used in iOS 4.1 to further spruce the resulting image up and make the colors pop.

It seems surprising that Apple could make any move to buy a company and not immediately be found out, but it appears that the acquisition went down under everyone’s nose back in July, with three Cupertino officers named directors of Imsense on July 15th, 2010. Could Apple once again be getting a tight grip on the secrecy they’ve lost handle of over the past year?

iOS 4.1 is now live, and along with the much anticipated software update comes Game Center, Apple’s new Xbox-Live-like gaming service that brings officially sanctioned achievements and multiplayer matchmaking to supported iPhones and iPod Touches.

Game Center seems promising, but unfortunately, it’s been hard to figure out exactly what games have Game Center support and which ones don’t… making early testing of the service frustrating. To make things easier, Apple has just updated the App Store with a dedicated Game Center section, highlighting all of the apps that have baked in Game Center support so far.

Unfortunately, most of the games currently on display are a little lackluster, with Flight Control, Fieldrunners and Zen Bound 2 being the real standouts… but hopefully that will change sooner rather than later.

Along with the arrival of sexy new iPod Touches replete with pixel-packed Retina Displays, touch-capable iPod Nanos and rollback Shuffles, today should see the debut of iOS 4.1 as well as Apple’s new iOS gaming social network, Game Center.

As such, TUAW is reporting that Game Center has just gone live for iPhone developers, meaning that instead of being limited to a sandbox-only development environment, Game Center is now allowing global registry and asking for new login details… older accounts having been purged from the system yesterday.

Game Center’s reportedly having a few birthing paints, including some crashing issues and connectivity problems, but it seems to mostly be due to server problems, and everything’s working once you manage to get connected.

Since Game Center is the showcase new functionality in iOS 4.1, the server switch being flipped on is a good indication that we’re all about to see an update get slurped down through iTunes sometime soon.

If you’re an iPhone 3G owner wondering if iOS 4.1 is going to save your device from the slow mercury hell of a sluggish post-3.1.3 device, good news. The fine lads and lasses over at Lifehacker find the last point iteration a marked improvement upon its predecessor, and to prove it, posted this chipper, chiptune-backed side-by-side comparison.

All I can say is, “Wow.” iOS 4.0 was that slow for 3G owners? How did Apple even let that update get out the door?

Too busy to read our liveblog coverage of Apple’s September iPod Event? Everything you need to know about Apple’s new products is below the fold, including details about the new iPod Shuffle, Nano, iPod Touch, AppleTV, iTunes and iOS update.

As you can see in the above screenshot, Apple has delivered on their improved signal bar graphics. Only time will tell if this is an actual indication of signal strength. Other noticeable changes include a revamp of the Game Center app, the ability to add FaceTime favorites and the Camera app (incl. camera roll) auto-rotating in landscape. More screenshots after the break.
