We have methods to get you back on the OTA path without losing apps and data if there are further leaks. However, it's been theorized that 230 will most likely be the OTA update unless a major bug is found between now and then. That's not to say it's 100% safe and that this will definitely be the update, but, it's likely to be. In any case, you can get back on the OTA path if this turns out not to be the final version.
