An original Bulgarian keyboard developed by Apple is expected to be included in the next OS for their popular iPhone.

There were settings for Bulgarian keyboard in the latest, 5th beta version of the OS, which came out yesterday.

The keyboard itself is still only in English. There is a language switch option, which supports languages like Romanian and Greek.

The developer of the first Bulgarian keyboard for iPhone – Atanas Chobanov – said that Bulgarian will be added along with a dictionary and a auto-correction tool.

It’s still unknown whether Apple chose the BDS or phonetic layout for Bulgarian input. At the website iphone-bulgaria.com, the phonetic input won by a very large margin. The final version of iPhone OS 3.0 will be released this summer.
