Quick tip, if you type in the phone dial pad "*#*#checkin#*#*" it will get the latest update if available. You will know you typed it correctly because it will say checking success. This will only checkin and see if it is there to download...it has to be there first
The 2.1 update botched my weather app, it crashes whenever I try to bring it up. And it made my phone slow as ass and it will crash sometimes, then I have to pull the battery and reboot.
