Now that the Idol 4 and the Idol 4s are official, Alcatel is understandably looking to clear some of its Idol 3 inventory, in anticipation of the release of the new devices. And that means there are deals to be had for last year's models. Both the 4.7-inch and the 5.5-inch Idol 3 variants are now cheaper at Amazon. The smaller handset can be yours for $169.99, which is $30 less than it was before. On the other hand, the 5.5" Idol 3 is priced at $179.99, a whopping $70 less than it was up until now. In both cases we're talking about phones you purchase unlocked and SIM-free, so there are no long-term carrier contracts to worry about here. If you're wondering which version to buy, then know that the 5.5-inch Idol 3 comes with better specs than its smaller sibling. So unless you feel that its size is too much to handle, it's probably the one to pick, especially now that it's just $10 more expensive than the 4.7-inch...
