Well, This just sucks. My first Eris had a blown speaker and made it so I could hardly hear it ring if it was in my pocket so I called up the store I bought it at and they had a new (refurb'd) unit shipped FedEx to me. I got it yesterday and wasn't able to do anything with it until very late in the evening. So I got it all activated and did the test call while talking to the rep on the land line. Everything seemed to work. So I put it on charge and went to bed. This morning I came into work and hadn't used the phone yet. The phone rings and I answer it. I hear a hello on the other end and then nothing. I think well WTF. So I call them back and nothing. I can't even hear it ringing on the other end, just a hum coming from the speaker on the back of the phone. I try this a few more times and say screw it and call them back on my office phone. In the meantime I do a battery pull and when it comes back up I am able to make a call and was talking for about 30 seconds and it did it again. At this point I am thinking it may be one of the 3 apps I installed on it. Google Voice, Mobile Defense and Zedge Ringtones. So I uninstalled all 3 and did another battery pull. I was able to talk again for about 30 seconds and this time the hum was considerably louder. So I do another battery pull and leave the battery out for quite a while. This time around I got about 10 seconds and I had to put my finger over the speaker because the hum was extremely loud. People 3 offices down heard it plain as day. I called the store and the first question they asked me if I had installed ATK and used it. I almost laughed at first. I told them the phone was junk and I wanted a replacement immediately. They said to bring it in and they would give me a new one.
