Sure, webOS 1.4.5 may finally be rolling out to Sprint Palm Pre and Pixi devices. Rather than rest on their laurels, though, Palm/HP and Sprint may already have another update prepped for users.  PreCentral has received a tip from their forum member and "presumed Sprint employee" that goes by the name leprecub has learned that Sprint will be pushing out webOS update 1.4.5.1 on July 7th.  On top of what the 1.4.5 update brings, 1.4.5.1 is said to contain the following upgrades and fixes:

Palm Pre Software Update to webOS 1.4.5.1
Customers: Palm Pre Users
Effective Date: 7/7/10

This should update your Sprint configuation to 2.5.

Details: A software update is available for the Palm Pre on 07/07/2010.
Fixes, Feature Updates and Enhancements

Web: Podcasts now download correctly.
Web: text entry can now be entered correctly
Email: Sprint branded default email signature correctly branded
Power consumption / battery optimization
Videos: A user can now send a video via multimedia messaging from the Video application
Video: the video trim feature now works to send in a message.
Sprint TV: Upgrade to V 3.5.4
Sprint TV: Enhanced Parental controls

All of these updates sound great, but I'm betting that the power consumption and battery optimizations are really going to please you Pre and Pixi owners.  After all, if your device sucks away all of your battery power, none of the other changes will even matter.  It sounds like webOS 1.4.5 hasn't hit everyone's handsets yet, so if this news is true, owners may as well just skip 1.4.5 and go right on to 1.4.5.1.  July 7th is only a couple of days away, so all will be revealed shortly!
