Replacement partsEither call Motorola at 1-866-BUY-MOTO or go to the Cellular Nationwide Network.
Headset adapterTo put it bluntly, the headphones that come with the L7 are junk. If you truly want to enjoy listening to music on your phone then you owe it to yourself to buy the Mini-USB (EMU) to 3.5mm adapter. This cable can be purchased directly from Cingular at this link. Scroll down the page a way and you will see it. It sells for $19.99. This cable makes all the difference in the world. I have a set of Bose Quiet Comfort 2 headphones and it makes my L7 sound as good as my iPod.
Phone cases and face platesSome places to do searches at are Amazon.com, Bargain Cells.com and Shopping.com. There are all kinds of cases from quality leather ones to cheap silicon. Face plates are easy to change and they come in every style you can imagine.
Dual phone/battery chargerSince I like having spare batteries, I found this little gadget that will charge both the L7 and a second battery at the same time. I like that it also has an LCD that tells you the charging status of both batteries at the same time. Tiger Direct has it for $19.99.
Screen protectorsYes a few people do. The ones I hear the most raves about are by a company called Martin Fields. You can get them here. Clear Touch also sells a similar product here. Clarivue makes yet another type here.
Use the L7 as a Bluetooth remote control for your MacHow would you like to use your phone to control the Front Row program on your Mac? The Salling Clicker controls iTunes, Keynote, PowerPoint, EyeTV, DVD Player, VLC, and more. It is ultra-extensible via AppleScript. It also supports wi-fi connectivity and works with PCs as well. The manufacturer offers a free 30 click trial version of the program and it costs $23.95 for the full version. You can get the program here.
