^^ EDGE does NOT Work. Even with Data Roaming enabled.
(It works with his SIM in another phone, namely N96)

An iPhone without Internet, is not an iPhone. Its just a Phone! . Ok, that sounded lame.

So, I wouldn't recommend YesSIM.
Still testing Virgin SIM, but preliminary results are brilliant. I think we have a winner. Although, Im not sure whatll happen when the next round of updates comes along.
