I have an iPhone 3GS (new bootrom) at 4.01 jailbroken with jailbreakme.com. My current problem is I just found out that the volume button on my headphones are not working. I tried in the phone app, ipod app, youtube app and skype and none of them worked. However, the microphone on the headphone is still working and I can use it for phone/skype calls. At first I thought my headphones broke down but the headphone volume button actually worked on my friend's iphone 3GS. I tried restarting or respringing but still no luck. I am guessing now that there is either something wrong with my hardware or there is something wrong with the iOS in my phone. The jailbreak apps I installed are bitesms, 3G unrestrictor, lockinfo, popup blocker and sbssettings. I noticed that Activator is installed as well but I never used it nor mess around with its settings and I checked the settings nothing have been assigned. I wanted to try restoring but I am just waiting for the new pwngetool to come out before I restore it. Any idea of what went wrong with my phone? It is still under warranty so I can always bring it back to apple store for a replacement if it is a hardware issue.
