The 1.0.3 update to your Palm Pre doesn't add any new apps, but it does fix a few things in Gmail, Contacts and Calendar syncing. Here's the changelog:

Feature changes to existing applications
Calendar

* Events created in your Google calendar-either in Calendar on your phone or in Google online-that contain a symbol or accented character in the event name can now synchronize. Previously, including a symbol or accented character in an event name prevented the event from synchronizing.
* Changes made to Google events on the phone now sync with Google online within a few minutes.
* The sync interval for Google events has been decreased from every few hours to every 15 minutes.

Clock

* If you create a weekday alarm on a weekend, the alarm sounds only on weekdays. Previously the alarm would sound on the weekend also.

Contacts

* Changes made to Google contacts on the phone now sync with Google online within a few minutes.
* The sync interval for Google contacts has been decreased from every few hours to every 15 minutes.

Email

* Power performance in areas where wireless coverage is sporadic or unavailable has been enhanced.
* Non-SSL Exchange ActiveSync (EAS) mail servers are now supported.

Other

* Miscellaneous updates for Email, Phone, and other applications.
