If I sign up my Moto X Pure Edition for the Motorola Feedback Network, will my phone work if I end up being selected for an update or soak test before it is completely released?
Nobody can be certain about the consequences of some future action. Me? I’d wait until RW has had a chance to evaluate the update to make certain the Republic app works with it.
Even if you aren’t on RW, your phone may not work properly with the beta (soak test). That’s the reason for the test, to identify problems. If you’re not tolerant to bugs, and happy to provide detailed failure information, beta testing is probably not for you.
