Yeah, don't know how or why...but in transfering my contacts from my iPhone 4 to this 9700, every contact shows the same number for "work" and "mobile" phones!
I guess I either have to manually delete one number per contact (ugh!) to keep the pop up from showing...or just live with it, and have one more click-per-call. Bummer...
Looks like I'll be busy awhile! Haha!
