My 3D had been running fine, but now there are all kinds of issues since I took the ICS update:
1. Sometimes the time jumps a couple of hours and you have to reboot to get it corrected.
2. Mail will show 99+ new messages when there are no new messages.
3. New photos will not show up in the gallery.
4. Voice dialing through bluetooth works maybe 50% of the time.
5. Battery is being sucked dry.
6. Apps like Battery Indicaator will just unload themselves.
7. Phone will sometimes put itself into airplane mode.
8. etc., etc. etc. Little things almost every day.
9. Sigh.
