In Ice Cream Sandwich, at least on all of the Motorola Droid Razr Maxx HD's that we have here and a couple of Droid Bionic's that have received the ICS update, we are finding that all contacts that synchronize into the phone from our Microsoft Exchange server show up on the phone with "WORK FAX" as the first number listed. I would think that there would be a way to make the Mobile # always show up as the first result when searching through and tapping on contacts. I have yet to find anyone who knows of a way to change this order. The only thing I've found is that if I delete the work fax # on the phone, and re-add it to the phone, it shows up last, leaving the other numbers first. This would be a large problem for dealing with multiple phones and 500+ contacts with fax numbers. Also, if for any reason the contacts had to get resynced or moved to a new phone, they show back up in the "work fax number first" order again. What does everyone think?
