Every time I get a new Windows Mobile phone, I have to hunt for a Chinese input solution that supports qwerty keyboard properly. I have trying to find a workable solution for my i780, and while A4, PlumSIP and GuoBi can be installed and used on my device, but they introduce some ‘side effects’ that makes me look elsewhere for better solution.
I did some web research and finally came to a conclusion that I can make use of some DLL files that I believe originated from Microsoft. Packaged them with proper registry settings, I can now finally type both Chinese and English text using my qwerty keyboard. The only issue is the symbol input button has become invalid, at least for now, but that’s not a big deal for me.
with a click of a button, the qwerty input is changed to Chinese mode.
also it comes with an interesting pin yin SIP, but I prefer using my qwerty keyboard.
For folks whose phones do not come with physical qwerty keyboard, you don’t need this since you can easily install those SIP software made available by the likes of PlumSIP, ZTA4, etc.
The above is tested well on i780, you are welcome to test on your non-i780 but qwerty phone. Do let me know if this can be installed/used properly on your qwerty phone.
You can download the CAB file from here
Update on 4th July: Found some problem the moment my i780 changes the resolution from 128dpi to 96dpi. Had managed to fix that, so if you encountered some error while trying to activate the PinYin SIP, you can try re-applying the latest fix from here
2nd Update on 4th July: For folks who don’t really need SIP (who needs SIP with a qwerty keyboard? :P), I have re-packaged a separate CAB to take away the SIP portion. You can download this PinYin “Lite” version from here

Dear Z:
I am a newbie, please bare with me. I just bought a Samsung i617. I am trying to resolve the same problem. I don’t know how you solve your Chinese display issue. In my case, I resort to install an Arial Unicode font on the device and change registry settings so everything uses that font. This is my way of ensuring both Traditional as well as Simplified Glyph can be displayed properly.
Would you give a pointer on how to map a hardware button on IME toggling? Once I installed your Zeeyeepinyin.cab, by default it’s Chinese input, and I don’t know how to get out of that.
And it seems that the keyboard mapping is not 100% neither.
thanks in advance for helping out. I want to see if your method works on Samsung i617 / 607 or not.

after you have installed the pinyin software, you would need to install multi-lang editor, and use the menu to set the english lang as your default lang for your phone. Also, you may want to try the latest PlumSIP 6.1 IME, which seems to support Chinese input while preserving the function of the physical keyboard.
hello. i can’t seem to type in my friend’s contact name in the SMS “To:” area anymore. It doesnt seem to help me complete my contact’s name.
How do i solve this problem?
the problem is due to the compime.dll which is responsible for the receipient lookup service. If you removed that away from your registry, you will lose this feature, unless the dll that you use to replace compime has that feature.
