Here’s a quick video I shot comparing application launching times on the iPhone 3G and 3GS, using PCalc as the test app.
Important Update: PCalc’s launch time on my old 3G was misleadingly slow in the first version of this video I posted. I erroneously still had an ad hoc beta build installed on the 3G, not the release version from the App Store. This link now points to a new fair comparison. The 3GS still comes out ahead easily, but not so dramatically. My apologies for the error. Trust me, PCalc does not take 10 seconds to launch on any iPhone.
A few other side-by-side 3G vs. 3GS comparisons:
