    Hello as beta 4 is too slow and less smooth I would like to get back to the beta 3 by doing a restore through itunes however I would like to know if I will be able to use my backup made with the beta 4 or no ?
    Thank you

    It should work since it's still iOS 9 but beware that betas all have expiration dates. We're very likely close to the expiration date for beta 3 and if you're on a beta when it expires, you will have to wipe the phone and restore from backup.

    I'm just basing it off history. All previous betas iOS 4 to iOS 8 had expiration dates. Better safe than sorry.

    iOS 9 betas have no expiration dates but I don't believe any of them are being signed anymore aside from beta 4.

    I already said you can't. Apple isn't signing any of the betas except for beta 4.

    I don't think you can. It's either last official release (8.4) or latest beta (9.0 beta 4)

    Just hold tight, beta 5 is around the corner and could be as soon as tomorrow, if not, then likely day this next Monday/Tuesday coming up.

    I tried going from PB2 to PB1 with no success. It doesn't appear to be possible.

    I haven't tried this exact circumstance but I was able to install Beta 1 after the fact that Beta 2 and 3 was released. However others are saying Apple isn't signing old beta so I don't know

    If someone points me to the file for B3 (I did not download that one from the developers site, I only have 1 & 4), I will be happy to try it. B4 is not allowing me to fully restore my iCloud backup so I am curious if B3 will.

    It won't work. Beta 3 is no longer being signed by Apple. There's nothing to try.

    I actually got it working without even restoring to ios 8.4 i just clicked on option + search for updates on itunes then i selected the beta 3 ipsw file and it was installed but only matter my sms wasn't backed up and I had to manually restore some apps.
