According to Bloomberg, one of the top financial news sources in the world, Palm has hired an investment banking giant Goldman Sachs to arrange a sale of the company, at least according to 3 people familiar with the situation (read: anonymous informants/insiders).
HTC and Lenovo are listed as potential bidders in a bidding that may happen as early as this week. Dell is also mentioned but said to have passed on making an offer.
Palm has been in financial trouble for years after its PDA and smartphone products had been overtaken by competition. The Pre, released on June 6 2009, was touted to be the silver bullet that would pull the company out of bankruptcy.
