I Vote 4. I have an EDGE Phone, but I am getting only the same speed as normal GPRS. My Service Provider is Vodafone. The charges for data connections is also very high. In my experience, it is also very inconvenient to browse the web using a mobile phone, except in Apple's iPhone (it is by far the best mobile for surfing; readability is superb and the display scaling is perfect).
I use GPRS/EDGE for checking e-mail via POP3, though. Never for surfing.
