Sounds good.

Just a note, on the "skelephone" that I use I replaced the GSM antenna
with a short length of patch wire, it still works (and some guy was
complaining normal GTA02 is for hardcore hackers).  I guess if I
shortened it further, it can force base station to tell me to use max
power all the time.  RF performance seems fine with $WIRE like 5cm long.
