Anyone else having strange issues with iMessage? My wife cannot send me an iMessage using my phone # but, she can using my email. I can send her an iMessage using either her phone number or her email. She is on an iPhone 4 and I'm on a 3GS ('til tomorrow). Why dosen't my phone number register as an iMessage device for her. I've checked our Message settings on both phones and they are the same; both our emails and phone #'s are listed under "receive at" addresses, both our caller ID's are set to each other's phone number. I can't figure it out; no matter what address I use for her, it goes through as an iMessage but, it only works for her if she uses my email. Need to figure this out since most people with iPhones will be using my phone number to text me.
