"Updating software failed. Would you like to try to update again?"
Uhm. . .yes?
Edit: Second time's a charm I guess. I'm restarting it after reformatting it again now. The first time it was super laggy because it was installing all of the items from my memory card, but I formatted it and we're starting over.
So far, the best thing I've noticed is that the pops and hisses are GONE, and I mean GONE while making phone calls, as someone else said. That alone is worth the upgrade. Calls are VERY clear.
