3G not much faster than 2.5G
This note points out that due to high latency in both 2.5G and 3G networks, performance can sometimes be almost the same despite a much higher raw bit performance in 3G. This is not good for web page browsing, but on the other hand might open the market for new technologies to override these problems (e.g. very large local caches, server-side removal of irrelevant data, sending the whole page as one file, etc). Even when downloading one single file can latency be a problem, as all such communication requires handshaking to secure that the right data has been received, and possibly resend sections thereof if not.

Own comments:
My experience is though that if the signal conditions are good there is actually a quite big difference in actual performance.
Regarding the comment about large caches: There will be so much memory in phones from now on that the page cache should be pretty big by default, unless manufacturers put up fixed boundaries for the cache and/or put the cache in Flash memory (that is slow when writing).
