The HTC One version can be downloaded right now from http://switch.modaco.com, please ensure you read the first few posts carefully before getting started, there's lots of useful information in there!
There has been a lot of interest in a version of Switch for the Galaxy S4 and it's something that we really want to happen. If it's something you are waiting for too (or you just want to support the overall development of the MoDaCo.SWITCH product) then head on over to this page on Indiegogo for more details.
Thanks for everyone's support throughout the whole Beta process!
