Thanks everybody for the response
I did install the new version last night (yes, the 8320 version). I found that Chinese characters display only in IE and Email, but unfortunately, not with Chinese ebooks in Mobipocket. I haven't tried the Memopad or any of the IM yet.
Overall, the new version seems to be slightly faster. However, I did experience one scenario with bluetooth. I was listening to the Media Player while driving this morning; and then initiated a call thru the BT in the car. Once the call ended, instead of resuming Media Player as in version 180, the Media Player stayed on pause. I'll test this scenario more later today.
Does anyone have similar problem with this version?
(Sorry for posting 8320 questions on a 8310 forum. I'll be more careful next time.)
