It's perfectly safe to swap battery while hooked to >= 500mA USB-power (GTA02 only! Never do this on GTA01 unless you know exactly what you're doing). Your considerations regarding GSM are correct, it needs a re-init after new bat inserted. Alas this seems to be a broken function in SHR atm. cheers jOERG
