I'm helping this dude jailbreak their iPod Touch, and I've come across a slight problem. The piezo speaker (the thing that makes the keyboard, and unlock sounds) is very faint. I don't remember how it was before it got jailbroken. There is still warranty for this, as it was from week 26. Should I restore it? Should I take it to Apple? Any other suggestions? If it's important, it's an 8GB Model with Firmware 2.2.
