I was poking around trying to decide which hybrid to make. I decided to make this post for those of you who are wondering where to get the older files:
8330 ESN Version -
.66 - US Cellular
.77 - Verizon, Carolina West Wireless, Cellcom, NTELOS, Virgin Mobile Canada
.127 - Alltel, Bell Mobility, CloseCall, MTS-BWA, SaskTel
.131 - CBeyond, Sprint
.138 - Appalachian Wireless, Bluegrass Wireless
.160 - Telus
These are from the official sites. If you are looking for another version, BING!
(I couldn't help it, everyone always says Google)
