Nciku releases iPhone app
Don't know if everyone is already aware of this and I'm just late to the party ...
Here's the blog post from a few days ago. Note that it's only an English-Chinese dictionary as of yet (no Chinese-English), but they're working on it.
Yep, I have that and some of the add-ons. It is excellent, but I like Nciku's sample sentences and other features. The thing that is holding me back from getting Nciku is that it needs the internet to do certain tasks.
