One simple request to solve my concern. Can we have a lock to installing / unistalling applications (password protect).

This will give me what I am looking for and I guess the good work of SMSCon can be used here.

Does upgrading firmware also remove SMSCon from the device. If so this limits its use till the device firmware is not changed.

I am sure that losing a device might be common, but losing it to some one wise enough to hack it is a less probable. But I want to lessen the chances of everything to make sure that I get my N900 if an ever if it is lost or stolen.

I love my phone and I am being very cautious to not lose it. I ordered it during the preorder days and didn't even get the rebate that Nokia announced .
