I been getting extreme lag with the iphone4S with the new OS. Sometimes I will go to click my message to look at a text and I can tap the screen 10 times for it responds then when it does it registers all my taps in like 6 seconds making the screen jump around like crazy. Also there are times where I will get a bulk of like 10 messages at a time that were sent 10 mins ago. I have had this issue on and off and took my phone to the apple store. They said I was having "spring board crashes" and reset my software by their computer and did a clean install. I didn't backup with my cloud just to see if it was really the software. Well it did it again. I went back to store and they swapped my phone under warranty. Now the new phone doing it ! What else can it be? Maybe an app? services? I just want to try and get this fixed it is so annoying. I try closing all apps, also hard resets but nothing seems to fix it.
