When I did, it was all running fine and dandy until I noticed that I haven't received a text all day.
When I restarted my phone I got a few texts at once.
I tried restoring, no fix.
Had to downgrade to 5b4.
Come to think about it my was a little tardy after upgrading to 5b5. This morning it's working as it should. Other than that I can't pin it on 5b5 or my carrier. Maybe try again?
