Palm, Inc. just informed PDAStreet that the software upgrade - Updater 1.10 - that delivers push e-mail and more to the Treo 700w is now back up on its Web site. The company took it down earlier in the week, after some users ran into trouble during the installation process.

Since the new download only includes changes that affect the installation process, those who've already successfully downloaded the 35 MB Updater 1.10 download and installed it need not do so again.

Palm provides the update to for the Windows Mobile-run Treo 700w with Verizon Wireless, currently the exclusive operator offering the smartphone. With push, when a server receives a message, it is automatically sent to a mobile device instead of the user having to manually pull it down or schedule retrievals at set intervals.

Push support is provided for enterprises with Microsoft's Messaging and Security wireless synchronization of e-mail, calendar, contacts and tasks with Exchange Server 2003 with Service Pack 2. Updater 1.10 brings the on-device Direct Push client or AKU2 (Adaptation Kit Update) to the Treo 700w, a Windows Mobile device.

Updater 1.10 also provides additional enhanced e-mail capabilities, including support for other push e-mail solutions, such as Wireless Sync, Verizon's e-mail solution for Domino and Exchange environments, and GoodLink; and enhanced synchronization with the ability to maintain an active data connection after POP or IMAP e-mail synchronizations, and the ability to auto-synchronize all e-mail accounts based on user settings.

There's also improved memory management as well as picture and video handling, and a new Wireless Manager that delivers an updated interface for turning wireless radios on and off on the Treo 700w.

Unfortunately, the update did not contain A2DP (stereo Bluetooth headset) support.
