Samsung do offer something like this, but only if you have a developer account. Requires a bit of setup though and you need to pay for a developer account. Best bet would be to test in simulator and try downloading a few android VM’s
Why not test the site on the mobile devices itself?
You can always upload the mobile site then visit a cell phone carrier or retailer store. Open your site up on all of their devices one by one then do your testing. It is free!
