Exactly, I totally agree with you, iMessage does not exist. So why is iOS5 on every other iPhone that has me as a contact attempts to send me an iMessage? I do not have it.
I believe this is because of the AppleID you used on the phone with iMessage. Your iMessage primary account is your AppleID and phone number. When you used the iOS 5 phone, your AppleID and phone number were registered with Apple as iMessage-enabled accounts and contact information. Now, when people send messages to you, it goes through iMessage but iMessage is unable to find an active iOS 5 device to send them to.
As mentioned, if you were able to update the current phone to iOS 5, you'd likely suddenly get a bunch of past iMessages that have been held up for all this time trying to send.
I suppose you could try contacting Apple to get your AppleID and phone number de-registered from iMessage?
Or, put it back into the iOS 5 phone, go into the settings and disable iMessage (although I am not sure that would really tell the server to stop processing your account or just disable it on the local device).
