Seems fine here - 3G signal which is surprising as I live in a signal void.
We have a special relationship with O2 (and vodafone/orange/etc); they call us to let us know about problems higher then P3.How do you have that info platypus?
All these problems at the time Apple are (rumoured) to be looking at offering the iPhone on different networks.
It's already confirmed that T-Mobile and Orange will be offering iPhone 3G [not the new 3GS... for now?] contracts in September/October.
Am I right in thinking that the settings in Cellular Data Network should be changed from the idata.o2.co.uk to mobile02.co.uk
