I fully rooted 2.1 and try to update with the OTA and it downloads but when it starts to update it says something like signature not valid. Then just has me reboot. What can i do to get 2.2 on my phone rooted or not. Also I tried to load the 1.47 RUU but i get a error code 170 and it never loads.

Please help if you can. Like I said i will go root or not. I just want 2.2

Thanks.
