Quite a few early adopters are claiming that their Hero refuses to hop on the carrier’s EV-DO Rev. A network. I took a look back at the company’s press release for the Hero, and sure enough, the Rev. A experience is promised.
It turns out that while the phone reads that it is operating at EV-DO Rev. 0, there is a message error in the UI that states this, even if the device is working on a Rev. A network. So, the good news is that this does not at all impact the operation of the phone – if you are in a EV-DO Rev. A coverage area, you will get Rev. A speeds.
According to HTC the message that Sprint Hero users are seeing is merely a mislabeling. If you’re within an EV-DO Rev. A area, you’ll get Rev. A speeds — despite that fact that your phone says it’s only on Rev. 0. A future maintenance release will address the message.
