Sorry but currently there is no difference between iPad and iPad 2.

See, there is no difference between the two of them:

iPad: 　Mozilla/5.0 (iPad; U; CPU OS 4_3 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8F190 Safari/6533.18.5 iPad2: 　Mozilla/5.0 (iPad; U; CPU OS 4_3 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8F191 Safari/6533.18.5 

And notice there, that the versions there are constantly changing in iOS updates.

UPDATE

LOL, but there is a difference between them:

iPad: Mobile/8F190 iPad 2: Mobile/8F191 iPad 3: Mobile/9B176 (according to Philipp)
