Okay, sorry if this is incredibly n00b of me.
I just got myself a Nokia 6630. Part of the reason for this was that I knew it can run Python, which is a language I'm familiar with. So when I got home, I went and downloaded the files I need. I got the SIS-package, 2nd edition and double clicked the PythonForSeries60.SIS file. Nokia Application Install applet runs, transfers the file to the phone, but then the phone is complaining about a security problem and doesn't offer any help to fix this.
Does anyone know this problem, preferably, of course, including a way to fix it?
