Before all the spectacular dual-core smartphones come out in the fall, Amazon has been cutting the prices of some of the most powerful and popular smartphone that were released a few months ago.
The price of the HTC ThunderBolt with a contract has been reduced to $49.99 while the Samsung Droid Charge has been reduced to $99 with a contract. Both support Verizon's 4G LTE network and have had good reviews (read ThuderBolt loads due or Droid Charge review) Here's how they fared when they were compared.
The Sprint Samsung Nexus S 4G can be bought for a penny with a new contract and comes with the pure Google experience. The Samsung Nexus S 4G will be replaced in the future with the Nexus Prime.
