I cant get this to work on Sendo X. Can people try this and let me know if this works on a Sendo X?

Wanted to share also my favourite tip for S60 users - how to easily toggle between Normal and Silent profiles. I'm sure most of you know that pressing the power key shortly will bring up a list of all profiles and allows easy switching to any of those. But there is an even faster way of toggling between Normal and Silent profiles - in case you need to do this frequently as I do, constantly running from one meeting to another - just press the #-key for a bit longer time. If you are currently using some other profile than Silent, then the phone will be turned to Silent. And from Silent, this will always take you to General profile. It's as simple as that.
