So about a month ago I got the 2.1 OTA update. I really liked the new features but it seemed really sluggish. I also had multiple problems. Someone would call and my phone wouldnt ring, but a minute later I got a missed call notification. My wife also has the Eris and hers has been a nightmare since the update. At first I thought she was nuts but I watched her try to call her dad. No lie, it took 10 minutes and 20 tries for it to go through. So anyway, reading the threads here I saw that other people were having the same problems. You guys rock BTW. It was suggested that we do a factory restart. Now we have had the update for a while, so starting over again was a reach. So I told her to suck it up (yup, did her phone first, sorry) and did it to her phone. The difference blew me away. Way WAY faster, and no phone issues at all. So of course I did mine as well. Same thing. Completely different phone. So here is what I learned. I have always used the swipe the pattern to unlock. It has always highlighted the circles in red. After I updated to 2.1 I had the same thing. Red circles. But after I did the factory reset the circles are now GREEN. And I have a completly new phone. So if youre having issues, try setting a lock pattern and check the color. If its red, do the factory reset. Im a complete newbe here, just wanted to pass on what I learned. Hope this helps some of you.
