We are not sure if this is a bug or a feature but if you try to push the power/sleep button for three times in a row on the lockscreen, the iPhone goes right into flashlight mode showing bright white screen. I have also tested this and it appears to be working on iPhone OS 4 Beta 4.

Some folks over at a Czech Republic site have closely examined the screen of one of the leaked prototype models of the next-iPhone under microscope and they have found it to be much denser than the current-gen iPhone 3GS model. This close examination of the screen has also confirmed the IPS panel screen (like iPad) for the next iPhone, with a high-resolution of 960×640 pixels.

There is a new modified version of PwnageTool floating around in the wild which promises to jailbreak iPhone 3GS on iPhone OS 4 Beta without upgrading the baseband. The creators of the original PwnageTool has confirmed that this version has been modified and redistributed without their permission, and most importantly, it doesn’t patches some important files which are required for the ultrasn0w unlock to work properly.

Redsn0w has just been updated to beta 4 to support the latest iPhone OS 4 Beta 4 firmware. iPhone OS 4 Beta 4 was released by Apple last week, which since Beta 2 has closed the jailbreak loophole used by Redsn0w 0.9.5b1 and b2 to jailbreak OS 4. But with this latest version of redsn0w, you should be able to jailbreak iPhone OS 4 again on iPhone 3G.

A group of hackers are working on bringing iPhone OS 4 over to the original iPhone EDGE (aka iPhone 2G) which was released back in 2007. Due to low memory and slower processing power, Apple decided to cut further upgrade support path for iPhone 2G in OS 4. The original iPhone EDGE users enjoyed all the firmware upgrades for free up to iPhone OS 3.1.3.

Chinese are known for cloning popular western products. They have done this to almost all Apple products in the past like iPod, iPhone and iPad.

Apple enthusiast site 9to5mac has managed to grab a screenshot from the latest version of iPhone OS 4, which shows a notification popping up in landscape view. While this is likely done in an error, there is still a remote possibility of Apple bringing such support to iPhone. After all, iPhone 3.2 for iPad supports landscape view, then why not on iPhone and iPod touch?

iPhone OS 4 Beta 2 was pushed to developers yesterday and it mainly brought API improvements, increased performance and bug fixes.
