Is the RTT really dominated by lightspeed delays and not processing in the phone?

The processing in the phone can be reliably removed from the equation using simple statistical methods.

Not unless a software patch on the phone introduces significant random variances into the RTT. But yeah, there will be no pretty way to make the network "think" you are actually near another far away tower. I bet, however, that this is still possible using a vulnerability in the "ping" method itself, like not sending a random nonce for authentication of responses (so that I couldn't send the "pong" before receiving the ping).
