Where in system files or in the phone is the OTA update.zip downloaded to? I'd like to pull it from the phone for archiving as well as use it to do a fresh system restore. I did the update this morning from 2.1 rooted, and the update went fine. With word of some people having problems after updating to the OTA from 2.1 rooted, I'm a bit nervous to do a factory restore. If anyone knows where to look in the phone for the OTA 2.3.15 update.zip, please let me know, thanks.
