careful. i had os 4.7 and it crashed my phone and gave me error 552 so i had to completely wipe it and reinstall. lost all apps. not worth it until you get official os5 loaded on it.
I'm having the same problem with .297 too. Fortunately it hasn't thrown an app error that it couldn't reset to resolve. Going to try to update app world and install it again. If that doesn't work, waiting till the 5.0 os comes out.
