Sidekick 4G that surely almost no one bought. While I still have a special love for the Sidekick, in this day and age of smartphones it's a dying breed. Sadly we have now learned the latest model, the Sidekick 4G has been retired by T-Mobile and is no more.
HTC EVO 4G, and I'm sure plenty expected it for the Kyocera Echo but today both of these Android smartphones have hit EOL (End of Life). Obviously the EVO 4G lasted much longer than the other and its reign has lasted a long time. Being the first 4.3" Android phone powered by 4G it was a sure hit and I still see the EVO 4G more than most to this day.
Droid 2 and Motorola Citrus are both soon being added to the EOL list along with a few other less important feature phones. We also see the Droid 3 is back-ordered and users might have a hard time finding it in stock for purchase.
