I tried googling this but didn't find much. I have an iPhone 4 and it's soooo slow lately. Hangs when switching apps, keyboard almost always has a 5 second delay before registering input, don't always get notified of text messages, etc. Has anyone seen performance improvement from clean installing iOS5 and NOT restoring from backup but setting up as a new phone? I want to know if there are any benefits from taking the time before I do this. Thanks in advance!
