the phone has been fully unlocked. no problem at all while on active mode - screen on (outgoing/incoming calls, sms, wifi... all are working fine). however, after i pressed the sleep button and the phone goes to sleep mode - screen off and leave the phone for 20 seconds. then i am not able to receive any call or sms. no missing call alert as well it just said "blah... please try again later". the phone is like turned off but it's on sleep mode only! once i press the home button and go back to the active mode - with screen on and all are working fine again. it's so annoying!

anyone got the same problem? what can i do... please help!...

Bumping this thread!! A friend of mine has the same problem and I have no clue why is that.

thanks! i really need help... could somebody help me out please?

i've been restored the phone and unlock it for several times already... the problem still exists...

I have this problem too. There is no cure for this so far. What method did you use for unlocking? Minicom? Or Unlock.pxl? Try to put your iPhone on charge, lock screnn, wait 20 sec and call on it - I think it will ring. It is strange thing...

thanks TapaH! i tried both minicom and unlock.app to unlock my phone but the hell probelm still exists... arrr...

That's what I'm talking about - trying minicom is a bad idea. A hell good way to unlock your phone is to use AppTapp, then PAYCAY, then last AnySIM or Unlock.pxl. And that's all. I trieв minicom and now - no wi-fi, no sound on incoming and battery dies in 6 hours.

i tried to put the phone on charge to the AC... and yes it works! gosh... how can i use the phone on the go??? it needs to be connected to the AC all the time in order to receive call... what a hi-tech wired phone! help~~~!

You have to fully restore it. Theoretically. But you cann't do it right now just because there is no way to do it now. So wait, like me, if you don't have possibility to get it back to the store and change.

Did anyone try to restore it directly in the iphone (setting- general- reset)? Maybe this is a solution? If I do this, do I lost the software unlock?

Hey have you guys tried to Virgin your phone (COMPLETE restore to factory)?
