M1
ask them for compensation...
same problem for me with IP4
but my colleague using M1 + android phones have no problem
not phone problem lah, my colleague sitting in front of me, both of us using 3GS, mine down but his ok. mine got signal, cannot call in but can call out

Maybe those with issue want to try to switch the phone back to 2G, it worked for me, at least. On 3G cannot get calls in/out.seems like my signal came back for a moment, all the smses came in, then it shows "no service" again. hopefully they are getting it back soon.
