My issues since upgrading to 1.1.1 have been:
--HORRIBLE speeds getting in to the SMS area... It will pull up what looks like the ichat window, only to have it sit there for 5-6 seconds. I usually delete any convos that get too full, so I know it isn't an issue of too many convo's in the window.
--Touch screen responsiveness. I feel that I have to be a lot more precise on where I touch, as well as touching for longer. I clean my screen daily, if not more.
--Assigned ringtone. Sometimes if someone calls where I have assigned a specific, Apple issues ringer, it won't ring with that ringer. Only the default. I then have to go into said contact, and verify the ringer is set, and then test it, to get the functionality back.
--A LOT of crashes when emailing photos from either the camera, or the photo albums. I can take a picture, and email it... New mail message will close, camera or album will crash, then I'll hear the "swoooosh!" of the outgoing mail message.
--I never receive MMS messages like I used to. Out of 10 messages sent to me, I would get all of them... Now, I only get about 2 out of those 10. A major pain!
--I also get that little play icon in the upper right. It's a pain in the a$$.
Nothing else.
