HK service provider 1010 (1010.hkcsl.com) also offers chinese support for the 7100. Although, it appears partial to me. As in, I can now read characters that I receive, but cannot write them. I installed their software on an unlocked 7100t (downloaded from:
http://1010.hkcsl.com/download/black....2.35-CSL.exe), and then I deleted the cross-vendor inhibitor files (search and delete "vendor.xml") and then used the update procedure to install the "chinese character support" package. But again, as noted above, there is still no chinese option under the language menu. But what was formerly black squares are now characters. It's very weird.
I assume it can be fixed but I don't know how. The only resource I found (on this page:
http://www.one2free.com/eng/blackberry/help.jsp) seem to indicate support is available only for other BB models. But I feel certain there must be writing support if there is reading support.
Anyone know?
