I'm sure, #2 is possible, but... you'd need to open support ticket to get the answer.
I was wondering still, if eth0 MAC same for everybody?
I dont think its same for everybody. I think it gets generated too, at first install.
I must admit Im not an expert in phones and ROMs and stuff like that, but I figure out that the IMSI and SIM serial # are generated on-the-fly by bluestacks when you change the GUID in registry, so I'm wondering where shall I look, see and modify the generating rules? Anybody ?!
Is there at least, a HARD way to do it, if not a simple one?
