We’re a little puzzled by the December 20th start date for a new software for the myTouch 4G as we’ve heard of myTouch 4G owners receiving an update since the middle of last week. While we attempt to sort that out, this “new” update begins tomorrow and will continue as an OTA roll-out through January 23rd and brings the following improvements:

• Google security update
• Turning off CMAS
• Locate GPS
• Fast dormancy
• Hotmail
• New version of swype

Not the most exciting of software updates but we’re never one to turn down anything that has bug fixes and improvements, no matter how trivial they may be.
