Tag: «iphone 4»

I have a French iPhone 4. Apple is required to cap headphone volume on phones sold in France — apparently to look after the citizens’ ears. In the metro that cap leaves me short on volume, and besides, headphones vary — some play louder, some have different impedance and play quieter.

The cap can be bypassed. You need to jailbreak the phone, then access the file system and tweak a couple of plist files. There are plenty of options — installing a Terminal via Cydia, mounting the phone as a drive on your computer, etc. I prefer the second route — installed Phone Disk, it mounted the phone as a volume, and from there I just rummaged through the file system.
