China Unicom was forced to stop taking iPhone 4 pre-orders after launch day saw 60,000 units sold and over 200,000 pre-orders. iPhone 4 inventory was wiped out shortly after Apple made the iPhone 4 available on September 25 through exclusive Chinese wireless carrier China Unicom and the Apple Store.

Shanghai and Beijing saw the opening of two new Apple retail stores on the same day. Over 1,000 people lined up outside the Beijing store up to two days in advance hoping to get their hands on an iPhone 4 before anyone else. The Chinese iPhone 4 launch came just three months after the device was launched in the US.

iPhone Dev-Team member MuscleNerd has posted a screenshot of his jailbroken iPod touch 4G. A bootrom vulnerability has been discovered by @p0sixninja that will make it possible to jailbreak all iOS devices running the latest firmware including the iPhone 4. Chronic Dev Team members are currently developing new jailbreak tools based on the vulnerability, otherwise known as SHAtter.

Evidence has surfaced that retailers are getting ready for Apple's white iPhone 4 launch. It's likely Apple would like to see the white model on shelves before the holiday shopping season. Screenshots of an internal inventory system at Canadian carrier Rogers Wireless have been leaked showing two white iPhone 4 models.

Like the black iPhone 4, white iPhones will be available in two storage capacities, 16GB and 32GB. Apparently Rogers has historically only added product information to the system if launch is imminent. Not to be outdone, US retailers are also prepping for the white iPhone 4 arrival.

Now you can store and run up to 2,160 iPhone apps on your home screen with iOS 4 folders. That's the maximum capacity with 180 folders holding 12 apps each. Although you may not come close to this limit folders are an excellent way to get organized and more efficiently use your iPhone.

Creating folders on the iPhone is simple and intuitive. Just drag one app on top of another app and a grey box will appear. iOS 4 will put both apps in the same folder and prompt you with a text box naming the folder. If you don't like the automatic name just type a new one in the box. Tapping the home screen will exit.

With the appropriately geeky tag line, "Take THAT BlackBerry!" the shopping website ThinkGeek has announced a flip-out physical keyboard accessory for the iPhone 4 and iPhone 3GS. The TK-421 iPhone case comes complete with a rotating hinge and its own built-in Bluetooth mini-keyboard.

The TK-421 is no iTwinge, but it does have a similarly odd name. The keyboard has its own USB-rechargeable battery and works with any application that already uses the on-screen keyboard. The product provides protection for the sides and back of the iPhone just like a case.
