Those fields are protected in the contacteditor, if I try to edit or insert a contact on my Pre minus webos 1.4.5. It is possible to save the other changes and sync them against Exchange. Changes in Exchange will be synced properly to the pre, I have to edit the contacts from another Exchange client. Thanks to Preware and 86 installed Packages (40 patches) the pre is very functional. Do I have to reset the phone to factory settings (and do all the work again)?
