There's always issues with being an early adopter for a gadget. Sometimes you get burned when companies start packaging accessories that they should have included in the first place! The picture shows an adapter that converts the ExtUSB on the G1 to a 3.5 mm headphone jack. These adapters didn't initially ship with the T-Mobile G1 (and we have no reason why) but are now being included into the packaging.
We're also hearing that some folks have gotten these adapters already with their G1. Anybody out there? And if you don't already have one of these adapters, maybe you can try your luck at charming a T-Mobile representative for a free one. They have great customer satisfaction, right?
