IPhone :: Any Fast Way To Add Number One In Front Of All Outgoing Calls?

Is there a fast way to add the number one in front of all out going calls? And also when setting up the phone number in the contacts list? My husband and I both have Iphones and I set up my phone numbers with the area code included. But recently when I called his phone, his phone never rang and went straight to voicemail. He did not receive the voicemail for more than an hour after I called him. If I had been in an emergency he would not have received the message. We called our provider ATT which had this answer.....even though I had the area code included I should have had the number one in front of the area code and then the call would have gone through.

ATT states that this is a "new regulation" that is going through the FCC. If that is true then I think 99.9% of the population has not heard of it. If that is true then why doesn't the newest phone - the Iphone 4S - have a capability to auto set the number one before dialing and auto set the fact that a phone number is required to have the area code with each phone number that is stored. I look forward to any resolutions to my question. Otherwise it is another manual job of going thru each phone contact and adding the information "required" by the FCC.
