We did anticipate the release of the 2.1 software for the Eris towards the end of the first quarter (March/April). As of right now we do have any official word of when it will be available. Sometimes these delays are as a result of last minute software changes that haven't met our expectations. I would like to be optimistic to say that we should have the software update sometime this month. In all honesty without an official statement from our product team, anything would be merely an educated guess.
I do encourage you to keep your eyes open for the software release. Normally the OTA software updates are pushed in phases. When the software is available you will be able to download it either from
