The HTC EVO Design 4G – you know, that little guy between the EVO 3D and EVO 4G LTE who so often gets forgotten – is getting an OTA update for itself, just a few short days after the OG EVO and EVO 3D got similar updates. This time, the software version has been bumped up to 4.02.651.2. Here’s the official changelog:

  • Hotspot improvements when on GSM network
  • Improved Messaging application ‘loading’ time
  • Sprint Connections Optimizer

According to Sprint, you can manually check for the update starting today, or you can wait to be notified on or after 2/26. This update means that all phones in the EVO family now have Sprint Connections Optimizer, which is a little tool that Sprint is implementing across practically all of its product line. The service runs transparently in the background and automatically connects you to WiFi or 4G WiMAX, if applicable. In other words, it’s a great way for Sprint to alleviate some of the congestion on its ailing 3G network.

If you notice any other changes or enhancements not listed here, or any new bugs, be sure to let us know.
