It appears the HTC EVO Design 4G has gotten a maintenance upgrade. Sprint didn’t mention what was changed, only opting to say “initial release” in its description. We imagine there isn’t much more than some bug fixes, but any fix is always good. You’re looking for version 1.19.651.0 and Sprint says it should take about 20 minutes to download. Head over to the source link for instructions how to find, download and install the update on your phone. [source, via]
