Firmware 1.1.2 is out, unofficially. The url to 1.1.2 firmware was posted in a Macrumors forum just now. Is this the US or EU firmware? I don't know. I'm probably going to hold off on this one in case there are variations between this and the official US release tomorrow. And for the sake of my apps, I might wait a few days after that. Here are some unconfirmed changes culled from the comments at Macrumors and Engadget:
•Battery charge level shown in iTunes.
•Does break the hack. Looks like they patched the TIFF exploit.
