Though just announced last week, Sprint has already begun selling Palm's Treo 755p. As noted, it is the first CDMA Treo to use an internalized antenna, and it is also the first Palm OS-based Treo to support Microsoft's Direct Push e-mail technology. Sprint confirms that the phone supports MP3 playback, and talk time is being rated at a healthy 4.2 hours. The phone costs $580 unlocked; this can be brought down to $280, however, with a two-year contract and a mail-in rebate. Blue and burgundy colors are available.
