Fix iPhone 3G rattle in under 6 seconds!
My Black iPhone 3G started rattling annoyingly after it suffered a little fall😱
The rattling is actually caused by part of the SIM ejector mechanism, as mentioned earlier in the thread.
It is easy to tell the difference between the slight rattling caused by the accelerometer, which sounds more suppressed and 'fixed', and the loose rattling which sounds like a tiny ball bearing is inside the iPhone caused by the SIM ejector mechanism.
To sort out the loose rattling sound, I just ejected the SIM tray, and replaced it. The rattling was gone😀 It took two attempts, but that was it!
The mechanism is perhaps slightly temperamental, but its worth giving this a few goes before going to the bother of replacing iPhone, if yours is otherwise perfect!😉
Hope this helps!🙂
