Hi again.
Thanks for the information...it helps!
To answer your question on upgrades to the Network coverage, as you highlighted, that is only through 02 itself.
But - Just recently, 48 upgraded the speed in which Data is transferred...you will find the full details on 'Techie updates' by techie Kev above the 'Help' Header on the forum.
The biggest factor we have if an incidence of regional or National Network issues occurs, is a flurry of Help posts hit the forum, in this case that has not happened.
To Quote, (regarding Network/Signal concerns...)
"There have been no changes to the O2’s 3G or Edge networks. So, if your 3G or Edge signal is poor because of your location, then unfortunately, that is not going to change. Often the O2 3G network is good outdoors, but then when you are indoors you can only pick up Edge."
This may be of no consolation to you, but informative at least.
At this point all i can suggest is to turn off the fone - remove battery and sim, replace & boot again.
Hopefully you will regain satisfactory operation.
