@cubiq - I just tried to ran your app on my webOS devices but had no luck so far. So these user-agent strings might be useful in case the devices are of any interest.

palm Pre Plus:

Mozilla/5.0 (webOS/2.1.0; U; en-GB) AppleWebKit/532.2 (KHTML, like Gecko) Version/1.0 Safari/532.2 Pre/1.1

HP TouchPad:

Mozilla/5.0 (hp-tablet; Linux; hpwOS/3.0.4; U; en-GB) AppleWebKit/534.6 (KHTML, like Gecko) wOSBrowser/234.76 Safari/534.6 TouchPad/1.0

An easy solution for all browsers is to ask the user to start in portrait > rotate > tap to confirm > rotate > tap to confirm > and so on. Maybe we could also check if the device is orientation aware and in that case send the confirmation tap automatically.

Regarding user agent spoofing there's little we can do about it. We could ask what browser/device the user is on at the beginning (trying to auto suggest our best bet looking at the user agent). This would mean making a list of all possibile combinations. Or you want the user to type his/hers browser and device?
