I will say this, I have been on t-mobile, and more recently vodafone for my phone. At first I had an iphone and now a galaxy s2. The signal with iphone on vodafone was hopeless at best and slightly better with the s2.
I am also on O2 for my ipad and i have to say, everywhere i go, theres a full signal and its very fast. I use the ipad as a sat nav when I fly and even 3000ft up and off the coast, I am able to download approach plates etc...
Next contract will be with O2, very impressed with them
