If you have an iPhone with 4.1 Jailbreak you can now surf privately on Safari by using the new free Covert app, which is available from the Cydia app store.
Redmond Pie have given the app the once over and said the private browsing is activated when a new tab is opened. You will not have to install a separate browser to make use of the apps features, just tap the Tabs button which is found on the bottom right toolbar of Safari and tap on “Private Browsing” to start a private session.
While a private browsing session is taking place the UI of the browser will change to a gray color, to show that any site which is now visited will not be traced. You will obviously need a jailbroken iPhone or iPod Touch to use this app. According to Redmond Pie Covert is available for free on Cydia under BigBoss repository.
