I am currently on Beta 3 as a non developer and when I go into settings it doesn't allow me to update anymore, it just says 'your software is up to date.' i've read on here that once the new beta (5) comes out, the previous one (4) is not pushed out anymore. So from here, can i just download 4 and press update on iTunes? Or do I have to do a restore of some sort. I'm trying to keep the data I have. TL;DR stuck on beta 3, non developer, tryna upgrade to beta 5 without losing any data. Thanks!
