For all those that just do ring tones and don't do third party apps, upgrade from 1.1.1 to 1.1.2. I finally upgraded to 1.1.1 and right away noticed there was now a slight lag and it was not smooth when you changed screens, like checking weather, stocks, ect. I was also only getting 1-2 bars of signal where I usually got 4 or 5. I kept 1.1.1. for about a month and just upgraded to 1.1.2. The lag went away and my signal strength is back to normal. So if you don't do third party apps, its worth upgrading.
