I've got a Nokia 3300 and I gather you should be able to plug any audio source IN, including a mic. I bought a powered Sony mic (as used with camcorders) and the right adapter for the minimini jack in, but can't get any signal, or nothing noticeable at least. It could be the mic but that seemed to work OK on other devices. Is the pin allocation on the jack different? or is my phone just deficient in this department? I'd like to use it as a recorder sometimes, it's one of the reasons i bought a 3300. Anyone eny experience of using the 3300 to record in this way?
