Hi,
I'm in county Clare and am also having Blackberry problems with O2.
Basically, I have been primarily getting only GSM signal for much of the time over the past few weeks in my house. When I drive to work every morning I get GPRS signal back at exactly the same spot on the road.
This I guess is because I am getting within range of another mast than the one servicing my home area.
I have called O2 to advise them of this but they INSIST there is no mast problem in my area so it must be a setting on my Blackberry.
Now how stupid is that, considering it works everywhere except around my home area.
