I really hope this iPhone patent gets implemented. Not because I personally need it, but because it's cool: Apple has designed a method to transfer messages or archives to whoever you are talking with on the phone, in real time:
While a user of a mobile device is using telephony services, the user may want to send a message or a file to another part. To send this information, the user may have to disconnect the call, and then perform a lookup of the caller's contact information prior to being able to send the message or file. This multi-step process can be tedious for the user.
