I can confirm there is no way to push/pull the update, it is released in waives, for example, receivers with receiver number r019****** - r024****** will get the update. and if you are r018 or lower, or r025 or higher, there is no way to get it. this is one EXAMPLE, there are other ways they can do it as well, geographically, and other ways.
there is NO WAY to force the update. just have to wait.
keep in mind, it is done that way to help squash any software bugs there might be, yes, you don't have the update (nor do I) but when we get it, it should be (basically) bug free, thanks to the people that have the update now.
