Today I got home from Nokia's Series 60 3rd Edition conference in Copenhagen. Unfortunately, the
presenters were not very coordinated, so they ended up saying the same things. Most of them talked
about the new security system in Symbian v9.1. A lot of changes has been made which breaks both
binaries and source code, and the new security model requires much work from the developers. For
example, you'll need to submit every application you want to release to a testing house to get it
certified, otherwise it won't run. This will cost time, money and hassle, and the decision was not
popular among the attendees. In theory it is a good idea to require all applications to be tested
and signed, but I think Symbian is taking this one step to far.
