Everyone likes free stuff right? The people at Letstalk.com think so too, so they have started running a contest where the winner will receive a brand new myTouch 4G. To enter the contest you can go to the official website HERE. From there you can then click on the "Enter Your Video button". You then just need to log in or sign up for a YouTube account, and submit a video. The video itself needs to be around 15 to 30 seconds long and explain what the Genius Button does and why it's awesome.
All of the entries recieved will be featured on the LetsTalk contest page, and the winner will actually be featured on the upcoming product page for the next myTouch. The contest is slated to end December 1st, and the winner will be announced right afterward. If it sounds interesting, and you dont mind a free phone for your creativity, remember to check out the official contest details/rules at Letstalk. Good luck!
