Ofcom published maps showing the approximate quality of 3G coverage from UK mobile providers yesterday. O2, home to the iPhone 3GS and the Palm Pre, did not fare well. And from your comments on the forums, it seems like that's a familiar story.
User Lubidog was first to voice their frustrations: "3G is not great on the iPhone to be honest. Often i have a strong signal and without moving an inch I lose it and can't get it back. It is so frustrating especially when I'm trying to stream radio over the 3G network."
Alexs was similarly annoyed: "O2's 3G service is shocking. I travel a lot around the South East of England and only have 3G reception for about 5-10% of the day. Worse still, when I come to use it, it normally drops back to Edge. My girlfriend has my old iPhone unlocked on Orange and gets 3G reception 90% of the time. O2 need to improve their network if they want to keep selling the best smartphones exclusively."
Skirtpatrick was more pragmatic about his struggles with signal: "Living in Northern Ireland, I had no expectation of any, let alone a good, 3G connection. I usually keep 3G turned off. I'm in range of a WiFi connection far more often than I am a 3G one."
And there was some good news for O2. Mike Bignell delivered this hymnal of praise to his 3G signal: "I get very good coverage with my iPhone. I get a consistent 3G signal everywhere I go with my iPhone. My other mobile on 3, struggles to stay on 3G at all."
