Recently I tried using the UK Three (3g) network. I got a nice new Nokia 6680 with half price for a year line rental. Problem was calls dropped at every opportunity and every time I rang the customer service centre I couldnt understand a word they said. Nice phone, too big - still. I found this good tip though for Nokia phones - reset them before you send them back or sell them on - key in *#7370# and it'll do a full reset.
10 x Dial Up Speeds
So, now I'm back on track with my Orange phone. I've tried www.onspeed.com recently and what they claim is true. I get 10x speed on GPRS dialled in.
I've also been impressed with www.skype.com with calls to Europe and theres a nice add on messaging system too. Calls to America seem to suffer from too much with delay/echo.
