I have acquired an iPhone 4 from Canada and I cannot unlock it with my Gevey Ultra- and I don't know why. I know my Gevey is legit because its works in another iPhone 4 with IOS 4.3.3 perfectly.
The only difference I can find between these 2 phones is the model and firmware.
Canadian MC603C / 03.10.01
American MC610LL / 04.10.01
Would that make a difference?
When I install the Gevey and power it on, it does nothing. No "accept" screen or anything. It just says "No Service".
Try to switch airplane mode on and then off again, could help tho, but not sure.. worth a try..
Or follow these few simple steps, they may or may not work:
Step 1. Turn off your iPhone & insert your SIM CARD & Gevey SIM together with the
metal SIM tray provided
Step 2. Turn on your iPhone & wait for the SIM welcome menu & then select accept
Step 3. Then wait 15 seconds, dial 112 then click on SEND hang up within 2
seconds. ( DO NOT let the call to take place )
Step 4. Then go to SETTINGS , & turn AIRPLANE MODE to ON & wait until you see
No Sim Card Installed & then turn off AIRPLANE MODE . Your Phone should have
signal after a few seconds.
But after 3 attempts it didnt work with the Vodafone SIM ( I think its an old model ), so
I switched for the Orange SIM it worked perfectly from the first attempt, then Ive
inserted the newly bought Cosmote SIM, I powered off the phone inserted the SIM &
powered on the device , slide the Unlock & a pop up menu appeared SIM Locked
Ive pressed Unlock, inserted the PIN number & waited
Pressed again OK still waiting
to unlock
I hit again OK for the 3rd time, eventually the SIM unlocked.
After that I got the message to accept the bla bla bla message that poped out, then I dialed
112 for 2 sec, all went well, continued with the instructions on step 4, settings & turn ON
AIRPLANE MODE , after this I waited for the No SIM Card INSTALLED , a popup
message came out ( SIM Failure ) then it closed automatically & got prompt again for the
PIN , I inserted the PIN but this time it unlocked from the first time.
After the PIN the beautiful signals appeared next to the LOGO of the Carrier
COSMOTE. I must confess that I jumped from my seat of happiness .
The internet Data plan worked fine without any trouble & the SIM had the full & glorious
5 bars .
