GPRS connection troube. Is it hardware?
 

Hi there!
I experience problems with my gprs connection on my n900
When i select gprs connection from connetions list, indicator (2 arrows in a circle) starts blinking, after that a message "Internet connecion failed Try again?" appears.
APN settings are correct, service is enabled.
I tried to fix it using 'flasher', but it did not help.
What else can i do?

Thanx
