I am sending messages to a person who has a new iphone4s so my messages should be blue and not counting towards my text. They start out blue then turn green getting sent as a text instead of iMessage
Could be temporary glitch in imessage servers. Try using both their cell# or apple id.
How do I use their apple ID?
Well they have to tell you what their apple id email is. You can simply select their email from the contacts list, or manually enter it in the "To:" field. It should also turn blue once the iMsg servers verify it.
