Re: SIMtrace phone-side VCC

for the MITM, there seem to be a couple of variables to play with (as compared to passive sniffing) that make it a little more reliable:

- wait for X number of power cycles, i.e. don't send ATR until the 3V3 one comes up - manipulate ATR: it seems possible to set the voltage class explicitly

The power-wait works for the BLU phone I mentioned, and the Nexus One. N1 also starts out with a different voltage (about 2.3V, weird..)
