iPhone 4, never jailbrake before, local DiGi set
it is something like this. the button work fine, but the software/firmware that got problem i suspect.
iPhone is not jailbroken, currently running on iOS 6.1.3 (believe it is the latest one)
anyone know how to solve this problem?

problem:
1. the volume bar did not appear when i press the volume button
2. all the applications are muted even though the mute button is not in mute position.

i have already tried:
1. Reset Setting in the Settings, Reset section
2. iOS update
3. DFU restore

the problem still occur after restore.

What do you mean is that download Ultrasnow in my iphone is it? I have Cydia already.
