Sprint has released software updates for both the HTC EVO 4G and the newer HTc EVO Design 4G. No, handset owners are not getting treated to Ice Cream Sandwich, but they will get a few system tweaks which include security updates, an updated Peep client and battery life improvements.

The OTA software updates will start popping up on the EVO 4G and Design 4G on January 24, but users can manually trigger the update as of January 19 by pressing Menu > Settings > System updates > HTC software update.

We’re not sure how big each update is, so let us know in the comments. We’d also love to hear hwo the update process goes and if you notice any significant system performance improvements after the installation. There’s still no work from HTC as to when/if these two devices will be updated to Android 4.0, but we won’t be surprised if the HTC EVO 4G finishes out its life on Gingerbread.
