Thanks Alexander, Stephen and Herminio.  I've learned a lesson here.  Make sure the device can be rooted before buying it.

If it is a AT&T device then you are dead in the water. There is no way to unlock the bootloader on those deives.

This really will vary depending on the device. And if you are still paying for it. If paid you can try the provider you bought it from.

There are lots of quality bootloader tools here. Also, lots of custom ROMs. Beware virus and spyware, only use ROMs the community vouches for, from known/respected people.

Does anyone know of a way to unlock the bootloader of an android device
