Hey, a little bit of confusion circulating with this one. So here's the story. Indosat posted OS official for the BlackBerry Storm 2 9520 but, mistakenly stuck it under the BlackBerry Storm 2 9550 slot on their website. This link, indeed leads to the install for the 9520. That said, if you want to get your official goodness on you now can. Just visit the Indosat BlackBerry download page and look under the 9550 section. No doubt someone will adjust this over time but for now, that's where it is.
