I have been having a problem with input lag/ incorrect inputs on my iphone 4 with the latest ios. typing is almost impossible with random inputs that i'm not making and lag with other inputs I make. trying to read an email today and it keep jumping around to reply , the forward , zoom , un zoom. For a brief moment I want to smash the thing. I have to hard reset 2 or 3 time in a row for it to go away. the problem stated 2 months ago and has been getting worse over time. I now have to hard reset almost everyday. I did a restore 2 weeks ago which help a little for a few days. any help would be great, as I would like to have most of the trouble shooting done before I call apple for help.
