I just wanted to chime in here with something I don’t think has been mentioned, which I feel is very important:
The limitations of iPhone caching (with OS3 and OS3.1. Hopefully Stoyan updates this for iOS4).
Stoyan Stefanov has some great findings at http://www.phpied.com/iphone-caching/
Some items I quickly gathered:
* iPhone will not cache components bigger than 15K (this is ungzipped size, meaning if you have for example a 20K JavaScript and your server sends it gzipped down to 10K, it will not be cached by the iPhone.)
* total cache is about 1.5MB
* powering off the device still clears all the cache
* consider HTML5 application cache to improve cacheability and provide offline experience
