With most Sony Ericsson devices to enter the service menu of the device >*<<*<*

with the Satio not having the correct keys to perform this task you need to press the following

red-green-red-red-green-red

*red being the end call key and green being the call/pick up key

Thanks, but not working on mine.

edit: Nevermind, now it works.

I'm taking a guess here but if normally its >*<<*<* then logically it should be...

...red-green-red-red-green-red-green

EDIT: Ignore this then as XELL's got it working.

Yep, you have to be very quick.

thanks mate its working fine with me

can u give me a link to download some useful applications for satio
