Version 1.3.5 promises the usual array of improved performance and enhancements for the two phones.
According to Palm, notable improvements include room for more apps and therefore eliminating the limitation on the number of apps that could be installed previously, better battery management and improved search functionality within the App store.
The update comes as rumours start to circle that Palm will announce Verizon versions of the Palm Pre and Pixi at CES 2010.
You can download the Palm Pre and Palm Pixi software from Palm's website.
We will keep you posted.
