Hi there, I've unlocked my 1.1.2 OTB and now i noticed that the ringing volume is too low. I maximized the volume control in the settings and set my ringtone to a custom one that i added and when it rings the sound is noisy but the volume is too low, even i can hardly hear it ringing when it is in my pocket.
I googled a little and find the iVolume and the way i can customize the master volume plist file but are they safe for the speaker?
As i said even without customizing the master volume file the custom ringtones playing noisy.

If it is safe to customize please tell me what number can i set to improve the sound volume without damaging its speaker.
