Hi all. I noticed that my friend's number, who i'm positive is an iPhone, is mobile, when I tap on their number. I went into their contact, but it says "mobile dimmed button." I don't kno why this is, except that i might've somehow messed up when they changed the number form a true mobile, to an iPhone. I can't undim the button, but when I click, it says iMessage. Has anyone seen this, and short of destroying the contact and recreating which I'd rather not, is there any advice? Thanks.
