If you, like myself, own an AT&T Palm Treo 680, you’d be interested to know that Palm has released a firmware update. The full details on the features added by the update are in The Official Palm Blog. As an overview, the update adds Push To Talk functionality, support for Microsoft Direct Push Technology, Instant Messaging for AIM, YIM, and MSN, support for 4GB SD/SDHC cards, enhanced ringtone support (use any MP3, AAC, AAC+, MIDI, WAV, or AMR file), and enhancements to power saving to prolong battery life. The update also refreshes the branding to reflect the change to AT&T from Cingular, and makes it easy to add additional services such as TeleNav GPS Navigator and MobiTV. It roll-up update, incorporating the past three AT&T 680 updates.
A version for unlocked Treo 680s will be available soon. You can sign up for notificationp of the release.
