Regarding two (or more) same IMEI of enabled phones - in one network this can
caused a collision - one of them can be blacklisted (the question is if it
was your clone or the original:)
In the worst case, this can be a nice phone DoS against the system :)

But according to this:
http://forum.gsmhosting.com/vbb/f131/what-will-happen-if-two-phones-same-imei-run-same-network-3965/

it should work:

I test it on two T10 in the same network & same room . We can speak with one fone with the other fine.

but probably these checks depends on the mobile provider.
