Sorry, didn't thought someone answered me already, so I deleted my post ^^

I had wifi disconnected on the phone, so really dumb move on my part !!!

Thanks anyway thedead1440

EDIT: seems like he deleted his post also. I'll leave this one here anyway, so maybe someone will avoid that silly mistake^^

Wow, sorry for double post, but this thing creeped me out: all those details of my device transfered on internet ! I realize I'm not ok with that, however trustful those people can be.

If I uninstall the app from the system menu of the n9, will it remove all unneeded dependencies and config files ? thx

Uninstalling should remove all the files installed by prey. You can double check if '/opt/prey' is deleted from the filesystem. Not sure about the dependencies though.
If you dont trust the Prey-project server people, you can operate Prey on standalone mode. In this mode you use your own server for tracking. More details and a server side app is available on the Prey website. The code is all open source and can be found here.

I haven't tested standalone mode, as I dont have a server.

Huge battery hog , drained full battery in 6 hours . In htop prey.sh was constantly on the top of processes . Now I purged it and never gonna install again any app of this kind .

Unable to trace installation dependencies!!!
