We have seen a tweet from AT&T confirming that they are working on Visual Voice Mail for Windows Phone 7.5, and now we have a slightly longer Facebook message saying the same.
The message provides interesting detail, such as that this was only added to Mango at a late date and therefore not included in testing, and that there will only be a “small delay“, suggesting we will see this feature implemented this year still. Great news for AT&T subscribers then.
Thanks JP for the tip.
