Apple has considered incorporating simultaneous file transfers during iPhone calls, a newly-published patent application shows. Though files can be uploaded through many different iPhone apps at present, the filing notes that in the middle of a call, it is currently impossible to send files or even text messages. It may also be necessary to quit a call to look up secondary contact info.

As a solution, Apple proposes a system in which a phone could automatically detect caller details, and through a revised interface send both files and text; this includes bringing up an onscreen keyboard as needed. The concept could be extended to a conference call, with the option of sending files to everyone or only individuals. In any case, receiving parties could choose to add contacts to their address books.

Communications could be sent through various different protocols, including Wi-Fi, WiMAX, Bluetooth or GSM/GPRS/EDGE. The patent was originally submitted in February of 2008. Credited with the invention is Peter Henry Mahowald.
