incoming call freezes when call from different carrier

[powa]

Guys I need help. I recently upgraded to 2.0.1 but I have problem for incoming calls. I can't slide to unlock. Until the caller ended. Then I can use the phone again. Does anyone know what I did wrong?

was wondering if you solved this issue?

i'm having the same problem with a 2g iphone on 3.0 jailbroken with very little cydia apps installed (winterboard, sbsettings). this problem started when it was still on 2.2.1. it doesn't happen to all calls and they're random and also doesn't restrict to only calls from other carriers.

we reboot the phone on a regular basis and doesn't have other problems, just that the screen freezes when an incoming call comes in and so can't answer the call and would go back to normal once the call goes into voicemail and shows up as a missed call.

any help and suggestion is appreciated
