To solve some common problems check out the myTouch 3G Troubleshooting Guide.
The HTC Magic, marketed as the T-Mobile myTouch 3G, is a smartphone first released in April, 2009. You can specifically identify the model of the phone by checking in the "about" section of the main menu of the phone's user interface.
The phone comes with a USB headphone adapter, wall charger, screen protector, a cloth pouch, and a USB cable.
The myTouch 3G was later succeeded by the myTouch 3G slide and the myTouch 4G. Both of which came out in 2010.
