If you’re using either the HTC EVO 4G or the Kyocera Echo, or if you’re planning to get your hands on either device (we’re not sure why you would), it looks like both products are headed towards their end of life, or so claims a leaked Sprint document that lists the devices that will be coming to their EOL. We’re not sure what this means for EVO 4G or Echo users and whether there will be continued updates and support, but this seems highly unlikely, but given the number of Android smartphones available in the market today, we’re sure you guys will find something new to love!
