I still have my old Motorola Droid 1 collecting dust around the house and my wife has an old flip phone (Motorola Entice). Can I just take the SIM card (that's what has the phone number on it, right?) out of the Entice and put it in my Droid 1? So that she can make/receive calls on the Droid 1 and use the apps etc just over wifi? I've searched around but wasn't able to find a definitive answer.
thnx,
Christoph
