Just when you thought you could go on rooting and switching ROMs with impunity, it turns out you can't -- at least, not if you want to continue enjoying your Google Music account. Watchful eyes at XDA Developers have discovered a snag in Google's authorization system, which means that not only is there an upper limit of ten devices that can be authorized simultaneously, but there's also a limit of four de-authorizations per year. Since every time you flash your phone or tablet counts as a new authorization, and since your other devices probably hog a few tickets already, rooters will quickly hit the ten-device limit, at which point they're going to have to think long and hard about their de-auth strategy. Is that a ration of one flash per quarter? But then what happens if you buy a new device in a few months' time? Oh, this is too much.
