I just downloaded a 1.3 Mb file in about 24 seconds, with speed averaging 50-60 K/s, peaking at 70 or 80 K/s here going through a Nokia 6120 classic. Latency is a bit worse than your average Wifi link, but still quite ok for browsing.

But actually I enjoy using Opera mini 4.0 so much on my Nokia 6120 that I always use that for occasional browsing when I'm outside.
