Chinese text input and output works just find on all Blackberry 7290s, and likely on other models. You’ll need to download a new version of the Blackberry OS for the Chinese market. Note that the Chinese input method (pinyin input) on the blackberry is not nearly as good as the Plum SIP (梅花输入法）that I use on my Palm Treo or the QIM Input Method that I use on my Mac.
Note, to toggle between Chinese and Roman input modes, you hit blackberry “shift” key (under the a, left of the z on my 7290) and the return key at the same time. You can download the Chinese Blackberry software from HKCSL: http://1010.hkcsl.com/blackberry
Select 1010 + Blackberry for Enterprises OR for Individuals, then select “Downloads”.
Or, you can just jup right to the HKCSL Blackberry Download Page
If you don’t already have the “Desktop Manager” software, you’ll need to grab that first. Here is a link to the current version: http://tinyurl.com/94hu9
Now that you’ve got the “Desktop Manager” installed, you’ll want to download the chinese version of the Blackberry 7290 operating system. http://tinyurl.com/b7row
Next, use the “Desktop Manager” to load the Blackberry 7290 firmware onto your device. In the Application Selection Window, make sure to select the pinyin input method. Note that you’ll probably get an error saying “INVALID SOFTWARE” or “INVALID VENDOR” when you try to do the install. To bypass this error, just delete the “vendor.xml” file, which should be located at:
C:\Program Files\Common Files\Research In Motion\AppLoader\vendor.xml
Once you’ve got it all installed, use the shortcut below to download RIM’s PDF on using the Chinese language features: toggling romanchinese, tone options, etc. http://tinyurl.com/bw7lu
Enjoy your new Chinese Blackberry!
