[mindly]

Thanks, tsac. Your idea would work, but it would take about as much work as the "last resort" I mentioned in my original post. Either way, I would have to go through my contacts one-by-one, see which ones lacked phone numbers, and take some action on each such contact (whether adding a single digit and then transferring all the contacts, or just transferring the contacts one by one without adding a digit). Hope that makes sense.

You're probably right that the new phone isn't seeing the contact's info the same way as the old phone.
