Sorry if my question proves my ignorance, but is there any ability to add the equivalent functionality of the iPhone's "visual voicemail" to an Android phone in NZ? I'm talking here about an app displaying each voice message received, and the ability to listen/delete etc directly from the app.

Essentially, I was wondering if there's an app that can be downloaded that provides this ability for use with NZ carriers; while I've found some apps that seem to perform this function (eg, InstaVoice), they seem to be specific to carriers in other countries (primarily the US).

Are there also no apps available that work completely independently from carriers' answer services? Ie, an app that "answers" your phone automatically after so many rings, plays a "leave a message" message, records the caller's message on the phone, then displays this for the owner to see and then listen/delete?

Thanks in advance for any illumination!
