A rumored tablet computer being built by a company in Nigeria became more credible over the weekend, when the company posted photos of a prototype on Facebook.

(In case you’re unaware: Nigeria’s national language is English, and the country’s population is roughly half Muslim and half Christian. Go back and re-read those get-rich-quick offers from Nigeria in your inbox. Do they make more sense now?)

Nigerian blogger Loy Okezie, a marketing consultant in the fast-growing New Lagos area on the country’s Atlantic coast, broke the story last week:

Encipher, a growing technology consultancy¬†based in the UK and founded by seasoned Nigerian technology entrepreneurs, Saheed Adepoju and Anibe Agamah is set to unveil the prototype of an Andriod powered tablet this weekend.”

In a later post, Okezie said that he had convinced Encipher’s founders to share the specs of their “work-in-progress” tablet. Its 7-inch 800×480-pixel touchscreen is smaller than Apple’s iPad. On the upside, a smaller screen may keep the device’s cost below Apple’s $500 entry level.

Encipher’s tablet runs on a Rockchip 2808 processor, with 512 megabytes of RAM and two gigabytes of solid-state file storage. The operating system is Google’s open-source Android. Wi-Fi is the only Internet connection available. There’s no Ethernet jack or 3G wireless.

Encipher doesn’t have a Web presence yet. But Adepoju told Okezie that Encipher’s business plan is to use the tablet as a means to sell cloud computing services — email, storage, backup, hosted desktops, VoIP phone service, and others.
