Orbitz has a promotion going on right now where you can get a free BlackBerry 6710 (a $99 value) if you book a flight, rent a car, reserve a hotel room, or buy a vacation package through their site. You do have to sign up a one year service subscription for $29.99 a month but you also get 85$ worth of mail-in rebates to cover the setup fee and the first month’s subscription costs. This is not a bad deal if you were already going to use Orbitz, but if you are just interested in getting a Blackberry, you can probably find similar offers from various handheld retailers on a variety of handheld units. This promotion runs through May 15th.
