I got a new droid x and its pretty cool. I don't want to pay 1000+$ a year for service. I just use it as an itouch. If any of you are doing the same thing, you probably noticed that the option to update to 2.2, is grayed out and the button does nothing. You don't need to do it over the air if you have wifi.
1) go into settings, wireless & network settings, mobile networks, system select
- choose "home only"
2)go into settings, about this phone
-you will notice that system updates is now available
-press sytem updates
-wait several minutes, it should go through eventually.
Pretty easy. It may seem to easy, but I have had a few questions and have been having trouble getting answers so I hope this helps someone, or makes it into a tips and tricks sticky somewhere. This doesn't void the warrenty and you don't need a computer.
Be sure to set your sevice free droid back to automatic because home will constantly use the battery looking for a network.
