Well lookie here. This one isn’t 100% confirmed just yet but a ninja hit us up with what could be some pretty juicy launch details for the rumor mill’s favorite handset du jour, the Palm Pre. Here we go — according to our ninja, Best Buy will be getting its hands on a limited inventory of Pre handsets for a trial launch on June 7th. Sprint will be direct-shipping the lot to arrive on the 6th and in total, about 4,500 units will be spread throughout Best Buy Mobile locations across the country. That might not seem like a lot, well, because it isn’t, but each and every Best Buy Mobile will be getting at least one Pre to hawk. Speaking of hawking, our ninja has some numbers to report as well. Pricing is supposedly still being discussed but the probable points are as follows: New customers with a 2-year contract, $199.99. Existing customer upgrades, $299.99. Outright, $999.99. Yes, seriously.
