Since the update I've noticed that imessages don't always work for me wondered if others experience the same.

You can select a contact, type a message and it won't send if you don't select the phone number that you want to use when you type in the contact name.

IOS will not remember or recall the number you selected previously to be used for that contact. So it won't allow the message to be sent, you have to delete the contact name from the message and then re-enter it and select one of the numbers stored under that contact.

It should be really easy to fix, when selecting a contact to iMessage IOS should only select phones stored under iPhone or Mobile header and always reference those numbers or display them as an option...

Anyone else experience this glitch where the system isn't allowing an iMessage to send because it doesn't have the phone number associated to the name in that message? Is there a switch to turn this off or is it a bug.
