hi i like to listen to internet radio stations due to the variety of music i can listen to and also due to the lack of full Flash support yet for 2.1 my 3G & HSDPA signal is excellent almost anywhere....at home, at work and on the road and out and about. i'm with T-mobile (UK) for the past 5 years and i'm very happy with their service. and the signal. but sometimes the internet radio still buffers sometimes even with an almost excellent signal. why is this? any explanation?
