The reason for EDGE is that it's US phone, nokia does not make US 3G phones as of yet (N75 is coming). Now, on the web-browsing portion. Don't get me wrong, it's pretty good when it works. Edge is not fast, but the page gets there eventually. Goal is to not install anything on the phone memory, keep everything on the memory card so you have max amount of space. You can browse say hofo or google mobile ok. However, say if you go to site heavy with images, after 10 min you will most likely get the memory full.
I haven't tried data transfer beyond 400-500KB, but that seems to work fine. It's web-page caching that kills you. The browser itself, btw, is very good, it's just device does not have quite enough ram, IMO. Don't forget, this has much better OS compared to yours, S60 and yours is S40, meaning lots of apps you can get. It has better keyboard, IMO, much better screen, more memory, etc... It's a better device hands down.
Its just there are a few drawbacks where you go and think, if someone spent a bit more time on design and testing, it would have been superb. Throw in 3G, more RAM, and 20% more screen space, and you would have a perfect device (well, better lense on the camera wouldn't hurt either

).
