Aside from the problems updating my iPhone 3GS 32GB and the horrendous issues regarding MobileMe/iCloud/Apple IDs, I am pleased to say iOS 5 is running great on my iPhone 3GS. Performance is on par with iOS 4, I wouldn't say better, but definitely not worse. Everything runs smoothly. Most notably, is battery life has improved immensely. I would put my iPhone in my pocket at 100% battery with iOS 4 and not use it almost the entire day, and have it left with 40% battery at the end of the day, sometimes with the battery dying at 30%, battery usually died at around 15%.
Today however, with iOS 5, I have used my iPhone A LOT more than usual, and the battery life fared better then when I don't even use my iPhone with iOS 4. After hours on my 3GS with iOS 5, the battery life went all the way down to 3%, I don't think thats ever happened before. I am pleased.
This all doesn't matter to me since I'm upgrading to a White iPhone 4S 64GB
