iPhone goes to sleep when opening voicemail

[smkkm5]

When I go into the phone section and click on voicemail ... I have 3 voicemails I click on the top one and the phone goes to sleep but I hear the voicemail playing or when I click on greeting it does the same thing... and no I am not covering the sensitive sensor area .... Is anyone having this problem? If its a firmware issue then everyone should be having this problem.



Iphone 3g 2.0 firmware
