There had been some rumors about the Samsung Lucello, a dual slider with a messaging focus, that was set to hit Sprint soon. Well, this device now has an official name and a release date. It’s called the Samsung M550 Exclaim and it’s set to release on Sprint on June 7th.

The interface is all about social networking with a menu that allows instant access to Facebook, MySpace and Google. As phones go, it’ pretty middle-of-the-road, with a 2-megapixel camera, Bluetooth and EVDO Rev 0. The Exclaim will be available in pink and blue flavors.

This isn’t 100% confirmed yet but the folks at BGR have some launch details for the the Palm Pre. Apparently Best Buy will be getting a limited inventory of 4,500 Pre handsets for a trial launch on June 7th. The story goes that Sprint will be direct-shipping them to arrive on the 6th. So, about 4,500 units will be spread throughout Best Buy Mobile locations across the country.

Yeah, that’s spreading them pretty thin. Rest assured that each and every Best Buy Mobile will be getting at least one Pre. Pricing is apparently still being decided on, but here’s what is likely: New customers with a 2-year contract, $199.99. Existing customer upgrades, $299.99. Outright, $999.99. Ouch!
