Hello people, i got my HyperCard today, everythign works except making calls, i can send, i can receive messages and also, can receive calls. When I call someone.. it rings.. for as long as i want, but if he/she picks up then it lasts for 2 seconds, i see there is no signal... It ends and after 2 seconds the signal is back. What can be the problem. Is it hardware or software related? Any ideas on how to fix it? My serviceprovider is EMT(Estonia).

I have tried with Caller id ... it's on, i can make a 2 second call, if it's off i can't call at all.
BL is 4.6 and FW is 1.1.2

I tried restoring it, went into DFU, restored to 1.1.1, jailbroke, 1.1.2, jailbroke and same thing. I installed iWorld before someone asks... i ran it too. I even put AppSupport template in. Any ideas on how to fix it?

try to upload via winscp the lockdown files. search for it, its here in this forum.

I think Hyper-Card has some problems, it was in my iPhone, worked poerfectly(not the calling part) and then suddenly it said no sim... Now, whatever i try, it says no sim, in my other phone as well.. I have two SIMs in Hyper-Card and there is still no SIM...

ok, i got it back online, i did the lockdownd files. did not work, and now my phone is very slow, can't even turn it off...

EDIT: restored it from scratch once again, devteams Jailbreak should include the lockdownd right.. so it still does not work, i can't call, i can send sms tho, i can receive both.

Now I have started to get these Invalid SIM messages as well. Still doesn't work, after everything i tried. Please someone help me.
