Conclusión

Amazon apparently discontinued service for this model: the service will expect double authentication, which apparently is not implemented in the Kindle firmware.

However, you can still use your Kindle 4 with USB : it is recognized as mass storage, and you can load ebooks in PDF or MOBI format in memory.

Check out the open-source software Caliber to convert your files in a vintage Kindle-friendly format.
