I know that there are a couple of posts that have this info, but I tried to get it to work and I don't know what im doing wrong. If anyone has detailed instructions please help me, I don't want this phone to go to waste.
There is a post in this forum that explains the internet and mms settings for att. HOWEVER in order to get the z8 to work with att mms messaging once you make the ATT profile all you do is go to options "proxy" check that off for proxy address input 66.209.11.61 and for port use port 8080. if 8080 don't work use port 80. That is all you have to do. without the proxy all will work but mms. you MUST use the proxy. simple as that. make sure you set mms to use your new att profile for the internet connection.
