Yesturday apple began to let web browsers on to the app store. All of these use apples WebKit as does Safari, and all offer special features that Safari does not yet offer. The browsers availible are Edge Browser, WebMate, Incognito, and Shaking Web. WebMate is only for 3G iPhones. Although Opera and Firefox are a long way off, these browsers are very nice to have. I have already tried Incogneto and Edge Browser. Edge Browser is for full screen browsing (the url is set in Settings). Incogneto deletes your session, not saving history, after every exit. I find that I use safari more than these other browsers but will get Firefox if it appears on the app store.
