Disable warning when using 3rd party accessories

[karl184]

Does anyone here know how to disable iPhone warnings when using "incompatible" 3rd party accessories? I'm using an iPod speaker with my iPhone and it works perfecly fine. It charges, plays music and even the remote works for it. There's also no GSM buzz at all when someone calls. However, it's a bit annoying that I receive the 3rd party warning everytime I dock it.
