I'd like to know what precise version of Mobile Safari the iPad I'm using has. Is there any way to find out (preferably from the device itself)? There doesn't seem to be any menu in Safari Mobile, and thus none to choose "About" from. If you go to Settings | Safari, you see various useful things, but no "About" or "Version" or similar, which surprised me.

+1 good question. Apparently Safari does not support any of the about: pages en.wikipedia.org/wiki/About_URI_scheme –  Thilo Nov 10 '11 at 4:53
@Thilo: But we should be kicking ourselves; it does, of course, support the javascript: pseudo-protocol. See Ross's answer. Doh!! –  T.J. Crowder Feb 26 '14 at 15:47

You can get the userAgent string without visiting an external website, by typing the following in the Safari address bar (where you would normally type a URL):


You must type it exactly as it appears here, matching case and punctuation.

An alert popup will appear with the full useragent string, which contains the version number of Safari and iOS.

What. Was. I. Thinking? Of course, the javascript: pseudo-protocol and navigator.userAgent. –  T.J. Crowder Feb 26 '14 at 15:46

Handy alternative if you want to copy paste this info / you're already there: plug your iPad into your mac (assuming platform!) and in OSX Safari, remote debug the device, and copy the User Agent from the Resource Panel under Request Headers.

Enable remote debugging:

  • In OSX Safari’s Preferences pane under Advanced, check the Show Develop menu in the menu bar checkbox.
  • On iDevice: Settings > Safari > Advanced

Could you explain why this works, not just a link. Just goiving a link makes me think of viruses and trojans etc. –  Mark May 9 '13 at 12:17
This works because on every request the browser send this information to the webserver. But usually you just do not see this and this webpage just "reflects" the information passed via the request. –  user72693 Mar 11 '14 at 9:50
