I kinda wish I didn't upgrade to ICS. My phone doesn't feel as fluid as it used to be on 2.3.6
Thats exctly how I feel. I kinda regret it.
Only pros I see are improved battery life and cleaner UIs on settings/apps. Other than that the screen sensitivity is messed up and some animations are choppy
does your phone freeze up a bit as well? I hate how screenshooting is so different on the phone now. I love the battery life now. My phone can actually last a day.
