sendrawpdu: send raw SMS PDU data to the iPhone 4 baseband

The little tool sendrawpdu is now on github. It is based on iphone-elite's sendmodem. With an iPhone 4, and this sample code, you can verify my statements for free ;-) .

By the way, I read some comments around saying that SMS spoofing is not new, that one can modify the origin address of a SMS in the protocol and such.

Now tell me, how can you do this without paying a dedicated service which is in fact a gateway talking to the carrier at a lower layer than the PDU data ? In a SMS-SUBMIT message, you can't change the origin address.
