Stock messaging and VVM apps

[jontalk]

A couple of noob questions..

1. VVM: Why would someone leaving a voicemail not show up on the VVM app which was installed and confirmed working by an ATT rep at a corp store. It had been working fine for the most part, but yesterday I rec'd a voice message that didn't show up there but instead had me using the dial in voice message retrieval which I'd prefer not to use. I was thinking that maybe this happened due to user error, or that I was in a weak signal area when the VM came in.. Who knows?

2. Stock messaging app: I have Skyvi installed on my phone and when I get text messages, I get the notification and it automatically opens Skyvi for a reply. When I reply the "1" in the bubble on the messaging app remains. In fact even when I reply manually using a keyboard the "1" remains there. Shouldn't it disappear after I reply? If I delete the message, it goes away of course.

Small things indeed. My phone has been pretty flawless for over 3 weeks now but it would be good to get these things resolved if possible. Thanks.
