I got my Moment in early April and loved it. I upgraded to 2.1 in early June. Over the past weekend my phone has become virtually useless. I have read about the "Airplane Bug", loss of data connection, etc. The other problems include, and are not limited too: -When I used my Starred Contacts added to my homepage, they do not call the correct numbers. Example: Select John Doe to call, and Jane Smith gets dialed. I thought I was misclicking at first, until I realized that the names getting mixed were not near each other in the list. -When I send a text message, I get: Code 7: Network Failure = Message Not Sent -I am missing calls. As in, my phone is not ringing and I am only getting voicemails long after the initial call. -People cannot get through to my phone, telling me it has repeatedy gone straight to voicemail. -The factory ESPN widget no longer works, however if I go via my Browser it works fine. -My battery life has been cut nearly in half, and I have tried numerous Task Killers/Managers and none have worked the same after my 2.1. -When I place a call, my data connection drops, and when I hang up it comes back. -After the screen rotates, it sticks. I do not have a bunch of Marketplace Apps on my phone either, mostly Google apps like My Tracks, and Voice. In short, I don't know what is going on with my phone. I am past the 30- day window to try it out and return and I don't think I will be able to make it much longer if the phone keeps acting the way that it has. Is there a fix for any of these or is it best to just take it back into the Sprint store?
