Loading new firmware, editing the registry or even unlocking your G1 to use on other carriers is one thing, but completely dismantling your device is definitely next level.  In a document leaked over at xda-developers, the website has been able to get their hands on the official HTC G1 Service Manual which goes into gory detail on everything from proper disassembly techniques, to pinouts, to part numbers, to testing methods and even beyond.  If you are a die-hard G1 owner then this is definitely a must-read, but we must warn you to proceed with caution before trying any of the information in this documents because it is sure to void your warranty.  On the other hand if $399 for a new G1 is pocket change, go ahead and certify yourself as a HTC G1 repair technician and have a blast.
