Can an unlocked 510 be locked again?

[gdesir]

I understand that you can unlock the icn510 and make it into a Pocketpc, and when you do a hard reboot it reverts back to the SmartSt software.

1. After rebooting, does it remove the Pocket pc program from the Memory card and wipe the existence of it?
3. Would you have to go through the whole install process for the pocketpc again or just start the program from a particular step?
2. is it possible to re-lock it back so that it appears that it has never been unlocked before, thus not voiding out your warranty?

I am curious how the TomTom 5 navigator works on my icn510, but I just wanted to know if I could revert the icn back to the factory defaults with out anyone know?
