Do the websites you mention (HSBC, Facebook) come up with the correct version on an Android phone? All you need to do is edit the iPhone UA string patch to use that of an Android phone (take your pick really) and websites would load as though the phone were an Android.

I've also tried a standard Pre 3 UA string with the KHTML Gecko part removed and simply added 'Mobile' after I noticed it was present in the Android string, but that didn't help.
Next up is a pilfered Android 2.3.5 UA String, I'll let you know how it goes.
BTW, the URL for the HSBC iphone site is www.hsbc.co.uk/1/2/mobile, you could try changing your bookmark with the default Pre 3 UA string and seeing if it still works. Trying it on my desktop (Chrome) redirects to hsbc.co.uk/1/2 (their standard home page) so it is definitely detecting standard/mobile browsers.
Double edit: removing the iPhone patch (back to standard Pre 3 UA string) and going to http://www.hsbc.co.uk/1/2/mobile does give you their mobile/iPhone site. You could try simply changing your bookmark for HSBC.
With Facebook, they seem to have recently unified their mobile versions. The iPhone version, the old touch.facebook.com, x.facebook.com, m.facebook.com, iphone.facebook.com all redirect to their latest one, the same on all platforms. i.facebook.com fails to load. You can try this on your desktop browser, Facebook doesn't seem to redirect.
Triple super edit: Using the Android string gives you the mobile versions of guardian.co.uk and hsbc.co.uk automatically (redirects), so that's good. No dice with Youtube though. You can click on a video and it simply does nothing, which I suppose is an improvement on the iPhone version, which complains about Safari plugins. App Catalog works though.
Obviously, none of this is perfect. The solution for the time-being seems to be to change your bookmark for HSBC to the one listed above.
