While Sprint did post a changelog for the webOS 1.4.5.1 update, it more or less confirms that the update will be released today – although it has yet to be confirmed whether the release has hit Sprint handsets already. Do leave a comment if your phone is running on webOS 1.4.5.1 already. Among the enhancements and fixes offered include correct downloading of Web podcasts, right entry of text on Web, correction of Sprint branded default email signature, optimized power and battery use, the ability to send video via multimedia messaging from the Video application, a video trim feature which functions when sending a message as well as enhanced parental controls with the upgrade of SprintTV to version 3.5.4.
