I was at the redbull flugtag
in London's hyde park today and I believe everyone was having troubles with there mobile phones. Well what do you expect with 70,000 people in a 3 mile radius? Anyhow i never had any such problem with phoning or texting with my 3g phone. Could be just because few people are on 3, or because it operates on a different frequency and/or its all data not voice. What ever it is, its good stuff at long last.
