Protecting or Limiting my account's power I have linked a great deal of power to my phone. It is connected to my gmail to such an extent that I am starting to get concerned that if somebody where to steal my phone they could reek havok on my life. Is there a way to limit my phone's account power with Google, and other companies. 

Example:

On my phone I can add, modify, and delete accounts. That is fine and dandy but I would be devastated if somebody deleted all my contacts and all my mail. Can I limit the accounts ability to delete stuff?
As far as I know there is no way that you can limit the ability of the phone to edit content.  That said there are many steps you can take to ensure that somebody won't be able to get to the stage where they can delete your content and dealing with it if it happens:


setup a pin number on your sim
setup a lock screen on your phone
install an application like SeekDroid and give it admin access so that you can remote wipe your phone if you lose it
install two factor authentication on all accounts which support it (Google, Dropbox, Facebook certainly do atm.  Others may)
make regular backups of anything you would be lost without, and store those backups in the cloud or in multiple places
don't use the same password more than once.  I use LastPass to ensure that all my passwords are all over 20 random characters.


You should really follow all of these steps - it adds a bit of overhead to some tasks, but I certainly favour the security over the convenience.
