While Mobile Safari was a trailblazer in terms of mobile browser experience, I get the impression Apple no longer cares about it since doing a 180 from their "no native apps" stance. It's phenomenal how often that thing crashes on my iPad (and just as often, apps displaying web pages inline via a UIWebView). I've had a look around to see if there are any alternatives for jailbroken devices, but all the other "browsers" seem to be UIWebView based. At least, leaving aside Opera Mini, which has its uses, but isn't really a full browser. Having a working Gecko or Chrome port or so would be a reason for me to jailbreak (or install it myself every 3 months via ad-hoc distribution using my developer account).
