Panoramic Software Inc. has released its first update for the iPhone version of Panoramic Calc Pro.
This version corrects several bugs, drastically improves support for non-english languages and adds some additional unit conversions.
I've been personally using it on my iPhone 3Gs with the device set to French and its been working perfectly.

At the time of writing its still on sale for the introductory price of 99 cents US but it will likely be going to $9.99 soon.
