I live in Renton, WA. I have a data connection, not the android plan, with APN using internet2.voicestream.com for internet connection. I didn't get the OTA update though I noticed attempted "Device Manager" connection with two diagnonal arrows shown in the left upper corner of the notification area briefly. I changed the APN to epc.tmobile.com and switch off/on the phone again. This time, the "Device Manager connecting" indicator remained on for about 20 minutes and showing 3G activities too. The screen suddenly pop up a message congratulating me for getting update software and asked me to continue. After clicking continue, the updating process began and took another 20-30 minutes to complete with a reboot. Checking the "about phone" messages, it indicated OS version 1.6. All these happened after 7:30am PST.
