Samsung Galaxy S v HTC Desire??

Does anybody know which 3 phones give the data-free access to MSN video calling?

To be honest, unless you're on Pay as you Go I really would avoid the Wildfire because you can get the Desire or Desire S for free on even the most basic contracts. You don't pay the ridiculous premium for it that you would with an iPhone

Worth noting that PAYG smartphones are available sub-£100. 3 have three of them here, for example
