Been running this for about 20 minutes and it's been running great. I did get one FC with the Wallpapers gallery when I was trying to change my wallpaper though. Also, I opened up Google Maps and the GPS locked on pretty quick. However, after closing maps I noticed the GPS icon on the top right corner didn't go away, and I had a notification about GPS finding my location, but I couldn't clear it. Then after that my phone started getting really hot. I just shut it down because I didn't want something bad to happen
Never felt my phone get that hot before. Going to put the battery back in and play with it some more. On a side note, ICS is FAST! And awesome!
