PocketPC e570, Is there an opportunity to set it...

you could set back the e570 factory default very easily.

On the left side of the pda you could find a small button, called RESET button.

You have to do these following steps:
The pda have to be turned off, then press the power button while pressing and holding the reset switch with the stylus, release the power button and when a screen appears, release the reset switch.

But be careful, when you reset your pda all data will be lost and make sure that all storage cards are removed!!!
