I've had my 4s for a while and enjoying Siri. Today my wife took the plunge and upgraded to the 4s as well. We share an Apple id, so when setting up her phone she put her contact information in Siri and everything worked great until later on when I used Siri on my phone and said "call my wife". A normal task that Siri has done hundreds of times, but this time she replied "who is your wife". Baffled I looked at the settings for Siri on my phone and her contact information was populated. Y can't u change the contacts for Siri on two different phones? If there is no work around then this sucks! I refuse to use 2 different Apple ids and pay for apps twice. Has anyone encountered this problem before?
