I can't help you with the answer to your exact question but could you mention in the notes section of the contact info page that certain contacts use an iPhone?
First, I must say I don't understand your question. So let me try to understand. Are you asking about the notes section because you believe that is a reasonable alternative to be able to have a record of which iPhones are, in fact, iPhones? Remember, the only motive I had to ID iPhones as iPhones was because I believed (hoped) that Apple had a legitimate purpose for allowing iPhone owners to, say, communicate uniquely with other iPhone owners but had to make that possible by identifying the universe of one iPhone user's fellow iPhone users. Was there a technical reason for "marking" certain mobiles uniquely? If the answer is NO, then why did Apple bother?
First, I would never blast someone trying to help me; yours is a legitimate question. I may have "forgotten" a few times at first to hit "DONE," but I'm pretty sure once I caught my mistake, I began, again, with the first contact and then, one-by-one, made sure every iPhone I "knew" was changed, if it was needed. Then on to the next, and the next... My magic question is: did Apple have any kind of reason allowing iPhones to be identified uniquely. To me, it makes no sense if there's not a technical reason.Mine are saved as iPhone for contacts I have designated as such. not sure what the issue could be with your phone. Don't blast me for this, but you are sure you are hitting "DONE" after editing?
I have some contacts listed as iPhones and some with iPhones that I never got around to changing from "mobile". Unless I'm missing something dramatic I can't tell any difference whatsoever with calls or messages. If they have iMessage enabled it works regardless of how you have their phone designated.
