Wiping data on an actual phone

Ok, usually I use the emulator so I have just to check the "wipe-dat开发者_StackOverflow中文版a" entry and that's it. If I'm using a phone how could I do that? Is there a way to have a "developer profile" on my phone so I don't lose my personal data?

I'm using my personal phone so....

If you go to Settings > Applications > Manage Applications > [particular application], there is an option to Clear Data. This will delete preferences etc. for the particular application. You can delete whole applications in the usual way through the menu, or with the adb uninstall [package name] command.
