Take a look at this post at Symbian's developer forum and especially the chapter describing new "Express signing" process. This looks like an improvement that at least I have been waiting for - it is a cheaper way to get applications signed and what's often more important, you will get the application signed immediately. Waiting for a week to get an application signed after a minor change has been something that I have felt quite difficult to explain to our customers.

This new signing process is expected to be available in Q4 and if you have any comments, now it is time to be active and provide constructive  feedback to Symbian people.
