I removed some of the APKs when i first rooted 2.1.. One example being Cityid. When i start the update to 2.1 it says that I failed because cityid is not there. I threw cityid on my sdcard and installed it, but still no luck. apparently its not in the folder still. I guess its like system/application/cityid.apk or something along those liines. I go into astro to try and copy and paste the apk to that folder and it wont allow me to. Also, i have no idea how to transfer the su from the one folder to the other. I tried in astro as well and it wont allow me. I would like to keep root if possible, if not, im sure we will be able to root 2.2 in the near future. Im new to this whole android thing, the X is my first one, im trying! i cant find my answer in any of the threads i keep reading.
