UPDATE: Just found that when the IDEOS is connected, a 7M drive with title "Mobile Partner" will be mounted to the computer that contains the device driver of the phone. So just install the driver in the folder will be fine.
If you want to use IDEOS as a development device, you will find that there is no device driver for this phone even you update the android SDK to the latest version. The IDEOS actually works on MacOSX or Linux as a development device.
iOS 4.1 於九月九日已經發放了，原來之前關閉掉的 field test 功能又回來了，有什麼用呢? 它可以更準確地告訴你電話的訊號強弱，而不用用那個小小的訊號圖示。
I was dealing with handling retina display in a project. According to the programming guide, I should change whether the screen is retina display or not by checking:
[[UIScreen mainScreen] scale]
that if scale is 2.0 it is retina display, if it is 1.0 it is normal display.
According to the document:
It should be available after OS 4.0. So I assume that:
An easy way to add twitter like pull down to refresh function to any table view. No dependency to other libraries, only include the 4 source files and 1 resource file to use it.

To support retina display, you need to set the scale of UIImage correctly. If you use UIGraphicsBeginImageContext to create offline image, you should use UIGraphicsBeginImageContextWithOptions instead to set the correct scale of the image. Below is the help function that will call with correct scale according to the scale of current device and will use the old function if the OS version of the device is below 4.0 that UIGraphicsBeginImageContextWithOptions is not available.
To use the code, simply replace all UIGraphicsBeginImageContext with RetinaAwareUIGraphicsBeginImageContext
