So i'd like to contribute my nice question for you all (even though i know the answer i think its a nice question that will get you guys exploring & thinking & digging through the java library).
Can you launch the Nokia store client from a midlet?
The use case for such is to link back to your publisher page and/or to help the user rate your app etc.
a simple enough question you'd think but not a simple enough answer because the answer is not a determinant Yes or No.
When you think about the answer think of the platform you working with (big difference between Series 40 and Symbian) and there are also other difference within the same platform.
