With little to no fanfare, it looks like the HTC EVO 3D is receiving another OTA update, albeit not as major as the last one.
Similar to the OTA application update that was ready for the EVO 3D shortly after launch day, this is another application update that only affects the HCAddProgramWidget and SPCSCorp4G.
This means that rooted users can safely apply this update, as it will only affect the above two applications. It does not require a stock recovery image and will not affect radios or the HBOOT.
There are no official release notes at this point, so we are not quite sure what, if any, bugs this fixes. However, I am intrigued at the update to SPCSCorp4G. If you are currently in a 4G area, please let us know if you notice any improvements or changes to your 4G connectivity.
To apply the update, just go to Settings > System updates > HTC Software update.
