I received a notice this morning that TMO had a software update available. I went through the process of updating, including installation. However, after the process, I received a message that the installation failed. I'm sure it's the 5.1.1 update since it was 143MB. I have no idea what happened. My phone shows it's still on 5.0.1. When I tried to go back to system updates, it tells me it's up to date. Did anyone else receive the update notice today? If so, did you have any problems with the update?
