I bought my G1 ebay and it turns out that I got the developer phone, which wasn't my intention. It came with version 1.1 and I really want to upgrade to 1.5. I rad htc.com and the google android developer site and manually upgrading the phone with their ADK is too complex for me. Is there soemthing else that I can do? I also downloaded that file that you are supposed to name update.zip and started the g1 with the home key down and pushed alt l and then alt-s, but when it runs the update package, it says that it's not signed or couldn't be verified. How else can I update to 1.5? Thanks!
