Apple Has Already Fixed Browser Security Hole

The hole in Safari has already been patched by Apple and they are preparing it for an upcoming software update, so make sure you back up your SHSH for your firmware so that you can restore back to it and use the JailbreakMe.com method to jailbreak your device. If your thinking of getting an iPhone 4 you better pick it up soon, because as soon as the new update is out you won’t be able to use the same exploit to jailbreak your phone.

On Wednesday an Apple spokeswoman said in a statement, “We’re aware of this reported issue, we have already developed a fix and it will be available to customers in an upcoming software update.”

How To: Protect Your iDevice From PDF Exploits

For all those of you who have used the JailbreakMe.com method of jailbreaking then you took advantage of a PDF exploit in the Safari application. This is good that you can jailbreak your device so easily but it also means anyone with the right know how can run code on your iDevice. This means that if in the wrong hands it could be used for malicious purposes.

The iPhone Dev-Team or Apple will eventually patch the PDF hole, probably the latter. For now you need to make sure your device is protected so that you don’t fall into any malicious traps. You need to install a Cydia package called PDF Loading Warner, this package displays a pop-up when your device is about to open a PDF. It won’t stop this exploit but it will let you choose not to open a PDF that might be malicious. It has caused some issues with iBooks when opening PDF files as you have to dismiss the pop-up numerous times. However it’s a small price to pay for such an easy jailbreak.

FaceTime uses 3MB of Data/Minute

The folks over at 9to5mac have found that FaceTime uses just under 3MB of data per minute. To be able to use FaceTime over 3G you need to jailbreak your iPhone 4 and then download the My3G app from Cydia. Then you can ‘trick’ the iOS into thinking it’s on WiFi when it’s actually using the 3G cellular network. Obviously this has it’s upsides such as using FaceTime where ever you like or watching high quality YouTube videos on the go. Bear in mind if your using FaceTime on 3G then take into your bandwidth cap into consideration. On O2 in the UK currently most iPhone 4 users have a 500MB+ cap. So if your on the 500MB plan then you can use FaceTime on 3G for a total of around 2 1/2 hours a month, that’s just on FaceTime. So make sure if you are using FaceTime on 3G that you don’t use it too much.

The Return of the JailbreakMe.com Jailbreak

Back in the 1.x days JailbreakMe.com was the simplest way to jailbreak your device. And now comex and Dev-Team have released the latest userland jailbreak which exploits a PDF flaw in MobileSafari. This means you can jailbreak any iOS device, including the iPhone4 on the 4.x firmware. Because the exploit that was used it public I’m sure it won’t be too long until Apple fix the flaw and then a new exploit will have to be used. As always remember to backup your SHSH files so that you can restore to your current firmware and keep on using JailbreakMe.com in the future.

To jailbreak just open up the site JailbreakMe.com and then slide to jailbreak and then just wait. It’s that simple!

iPhone 4 Screen Issues

Today the iPhone 4 was launched in many countries however a few big problems have arisen. The first one being the retina display which on 1000’s of users iPhone 4 is showing a yellow tint in parts of the screen.

However there has been a follow up on this issue someone posting on the AppleInsider forums seems to know why:

Apple is using a bonding agent called Organofunctional Silane Z-6011 to bond the layers of glass. Apparently, Apple (or more likely Foxconn) is shipping these products so quickly that the evaporation process is not complete. However, after one or two days of use, especially with the screen on, will complete the evaporation process and the yellow “blotches” will disappear. How do I know? I was involved in pitching Z-6011 to Apple.
So if this is true then we might see this problem clear within a few days as if not Apple is going to have a huge problem, seeing as in a recent Engadget poll 55% of users said there screen had the yellow colouring issue, which out of a sample of 27,640 people is quite shocking to say the least. This isn’t the only issue of the day that is affecting users but the new revolutionary antenna system seems to be causing big issues with reception and dropped calls, although Apple says it doesn’t it’s just to do with how the signal is displayed.

iOS 4 Custom Firmware (w/iBooks Fix)

Yesterday I provided you with Custom Firmware Restore files for all the iDevices that support the new update and can be jailbroken. This morning the Dev-Team released an update as it had the same issue as redsn0w to cause a problem with iBooks. Obviously if you don’t intend on using iBooks you don’t need to re-download it but I will be re-uploading the firmwares (without custom boot logos) with the fix for iBooks.
