UTStarcom PPC-6700 / XV-6700 / HTC Apache

Does anyone know how to change/edit the "Send Text Message" number listed in contacts? The number automatically defaults to the contact's cell phone number. I have my phone number blocked automatically, so when I program my contact numbers and want my number revealed I put *82 in front of the number, but that plugs into the text message section. The contacts shows the text message number, but will not allow direct editing. I currently plug the number in the pager section instead to select the number to text to.

Contacted Verizon...and I'm sure we all know how helpless they are about their products.

Thanks for any help on this!
