Some G1 Accessories You Might Need

Bluetooth headsets seem to work fine on the whole, but the device doesn't yet support stereo over bluetooth, so any audio playback will be mono sound only. This will be fixed with the next update, so there is no need to wait to buy your bluetooth headset.

The wired headset that comes with the G1 phone gives good sound quality, but the limitation of the phone is that it doesn't have a regular headphone/earphone socket, so for wired Google phone accessories you have to buy those that are specifically designed to be compatible with the Google phone.

However, in the US the G1 now ships with an adaptor which allows you to plug in a regular 3.5mm headset.

File Transfer - You Might Need a USB Data Cable

As yet Android doesn't support file transfer between the phone and your computer by Bluetooth. This should be added with the next update. Because this feature is actually missing from the underlying structure of the operating system, it's almost impossible for somebody else to add it (through a downloaded application for example) until the update.

File transfer over the USB cable works fine, although the method has changed from the Quick Start guide that comes with the phone, which has confused some people (me included). When you plug the USB cable in, a prompt will come up on the G1's notifications area (the pulldown at the top of the screen), saying "USB Connected - select to copy files to/from your computer". Tap the message, and when the next box pops up on screen select "Mount". After that, your computer will see the G1's SD card as an external drive, just like a Flash drive.

Everything the phone has stored on your SD card is organized pretty clearly, and your digital photos are under the folder called "dcim". You can copy your music, photos etc. into any folder and the G1's software should find them.
