There is not much defference between Safari 1.1.4 and 2.0. But Under the hood, MobileSafari 2.0's performance is hugely improved over 1.1.4. Everything related to web surfing feels faster, web pages consistently load faster on 2.0, both via Wi-Fi and EDGE. This has nothing to do with the new iPhone 3G hardware — this is about dramatic performance improvements on original iPhones upgraded to the 2.0 OS.
In August last year,
|Test||1.0.1||1.1.4||2.0||Vs. 1.0.1 / 1.1.4|
|100,000 iterations||3.209||1.096||0.145||22× / 8×|
|10,000 divisions||0.413||0.181||0.029||14× / 6×|
|10,000 sin(x) calls||0.709||0.373||0.140||5× / 3×|

|10,000 function calls||0.904||0.595||0.115||8× / 5×|
The last column shows how many times faster the 2.0 version of MobileSafari was versus 1.0.1 and 1.1.4. The same results, charted (smaller bars are faster) can be viewed above.
For all the hubbub regarding the new App Store, most “iPhone software” runs in the web browser. But improvements in WebKit performance often help native iPhone app performance, too — a slew of my favorite native iPhone apps have built-in WebKit browsers (e.g., NetNewsWire, Twitterrific, Instapaper, and Cocktails). When WebKit performance improves, any app that uses WebKit improves, and WebKit improved a lot between iPhone 1.1.4 and 2.0.0.
