There are rumors flying all around about a possible Sidekick successor. Both TmoNews and PhoneDog are reporting that there is a new HTC phone in the works codenamed Project Emerald that will be the next Sidekick. No really, like with the Sidekick name not just another phone meant to take the place of the Sidekick. There’s speculation that it will be called the Sidekick Twist, but of course that could change before launch, which people are guessing is “summer”. Of course this is all still rumors, but here’s what TmoNews is saying about the specs on this new device:

[…] we hear the device will boast Android OS 2.1, a 1 GHz Processor (Snapdragon?), with a front facing Camera and a 4.3-inch Super AMOLED display. This new device will also be flaunting 16GB of onboard storage with T-Mobile preloaded apps for active lifestyle oriented apps

As most of you know, the name “Sidekick” is owned by T-Mobile, not Danger/Microsoft. T-Mobile can use the name to market whatever phone they want. Previous Sidekicks were manufactured by Sharp or Motorola (the Slide), and this new phone is rumored to be made by HTC. With it running Android, that means no Danger OS and no back-end over the air syncing like in the past. With all of these changes, there’s a big question to be answered: Is it still a Sidekick?
