    Default Visual Voicemail is an AT&T service or an iPhone feature?

    I mean, has anybody checked if after a message is arrived free memory in the iPhone is the same or is less? I was wondering if the unlock have to deal with this too...

    The short answer is that it's both.

    Visual voicemail messages are downloaded to the iPhone, as evidenced by the fact that you can still listen to them when out of coverage or even in Airplane Mode. Changes such as deletions are replicated back to the AT&T servers the next time you're online (and vice-versa if you've checked your messages the traditional way).

    There are also indications that SMS plays a role in notifying the iPhone that there are new messages to collect from the network.

    Obviously the network itself has to support this, and apparently the visual voicemail boxes are on a different server from the normal subscriber voicemailboxes.

    So, with my actual carrier, when someone leaves a message in my box I receive an sms; than I could write an application that calls to my voicemail box, simulates pressing a couple of keys and saves the message somewhere inside the phone.
    This could open Visula Voicemail to people from overseas... (I'm not a software developer, so forgive me if what i'm saying is not appropriate).

    even thou it could be possible, this would be very unstable.
    why? first of all, some provider tell you first the time, then the massage, other first the massage then the time etc.

    its also not always the same duration for the number (111 is shorter than 555).
    and as soon as a provider changes a little thing, the whole programm needs to be reconfigured.

    then there would be a need of a speech-recognition for "zero seven nine" into "079".

    to do this, its just too complicated and too unstable (as said, the provider changes a bit, and the whole system is wrong). then again, there are a total of maaany many different providers, and there is no standart saying "first 10 seconds for number, then 10 seconds for date".

    just accept that this is too complicated.

    as soon as you have the massage, its easy to do, but till you get the massage, good luck
