    So i'm new to this android scene, but i'm ready to dive in. I just want to make sure of some things before i brick my phone.

    I got this phone from my sister and hasn't been used in a long time. It's running now, but the firmware is out of date

    Model number:
    T-Mobile G1
    Firmware version:
    1.0
    Baseband version:
    62.33.20.08H_1.22.12.29
    Kernel version:
    2.6.25-01843-gfea26b0 android-build@apa27 #6
    Build number:
    kila-user 1.0 TC4-RC29 115247 ota-rel-keys,release-keys

    i was going to follow these instructions for updating to Froyo. [ROM][BBQ] CyanogenMod-6 for Dream & Magic - V6.0.0 (08/28/2010) - xda-developers
    but they are a bit confusing.

    I guess i have to install a boot loader, CyanogenMod 6.0.0-DS and i'm following these instructions
    Dream:Installing CyanogenMod 5+ - CyanogenMod Wiki

    i downloaded
    latest CyanogenMod ROM: update-cm-6.0.0-DS-signed
    latest EBI1 kernel: bc-4.2.15.1-ebi1-signed
    latest Google Apps: gapps-ds-ERE36B-signed

    my question is that it says to copy them as update.zip to the root of the phone. but there are 3 of them. How can they all be named as the same, but at the root of sd card?

    can someone clarify this for me. or tell me i'm doing something wrong

    Wow I can't believe you have a g1 running firmware 1.0, even moreso though you have the RC29 build which would make rooting as easy as it gets. Unfortunately I can't help you with your question since I haven't had a g1 in over a year. I don't remember the steps. You'd be best asking this question in the G1 - All Things Root - Android Forums forum though.

    First question. Are you looking to have Cyanogens custom ROM installed, or would you be satisfied with the ROM that HTC would provide you? If the HTC version is a-ok by you, just hook it up to wifi and wait for the update to come automagically.

    If custom firmware is what tickles your fancy, the first thing you'll want to do is get a custom bootloader installed to your phone. Last I checked, Amon-Ra was the weapon of choice. Once you get that bootloader up and running you can install any zip that is loaded to your sdcard without the need to rename them to update.zip

    i don't think there is any reason for a custom rom, so the htc flavor is fine for me.

    I have been connected through the data network, but there hasn't been any prompt to update. I've tried going to google to download the firmware but every link i've come to has lead me to a 404 page

    You would actually need a custom rom if you want to run Android 2.1 or 2.2. The highest version of firmware officially supported on the G1 is 1.6.
