how realiable is your gvvm? I just switched to it from verizons version and it seems like i'm not getting all my messages. Sometimes i'll have voicemails that play nothing for a long time, some will start in the middle of the conversation, etc. What annoys me the most is that sometimes it seems it will go to the verizon voicemail box as I'll get a text from verizon stating i have a voicemail.Anyone else have that problem?
