Please define "unresponsive" and "reset" in the contexts to which you're referring. Is the phone freezing? Or going to a blank screen from which the home button does not awake? When you're "resetting" it, are you turning it off and on again or just back on? Your wording leaves a bit to confusion.
So what are you doing then? To me a "soft reset" is pressing the lock button until the red slider appears at the top, then sliding it off, then pressing the lock button again to turn it on. Another way to turn it off would be to hold down the home and lock button for 5 seconds. Holding them 7 seconds will then turn the phone on again.
I just can't quite visualize your situation. The phone is on, you're doing something, all of a sudden... blank screen? Then you... what?
lol no i have my phone on and maybe after a couple of hours when i go to make a call or something its suddenly off then it seems that the only way to turn it back on is to do a hard reset...
(i got confused before with the soft reset)
No, the only thing that gets affected here is stuff in the settings page... auto-lock time, screen brightness, contact sort order...that sort of stuff. You'll just have to step through all those categories and put them back to how you want them. Takes a minute at the most.
