iPhone 4G 5.0.1, 04.10.01 Gevey unlock

[kachijs]

Hey.

So here is my problem. I bought iphone 4 with Gevey supreme (at the start i didnt know much about these unlocking cards) but now i know it was a fake card that actually worked, but i had some problems:

When my 3G network was on i could not receive calls nor sms. If EDGE is one i have no problem.
Sometimes i just could not make a call (but i could receive call) When i turn on flight mode and turn it off all was back to normal.

So i came across ApplenBerry Gevey Ultra SIM card. So i thought if mine gevey supreme was fake the legit one will fix problems that i had.

I received my gevey but still problems remain. When 3G network is on i cannot receive calls
Second problem (that seems to be resolved by legit card).

my fw 5.0.1 , mdm fw 04.10.01

Who's the service provider now that your unlocked 3G will be compared to that
