My first Samsung smartphone was Omnia Pro GTB7610 bought it back in December 2009 and it ran Windows Mobile 6.1 professional.
I still have it, it's fully functional and and the battery holds charge.
Specs:
Processor: Samsung S3C6410 800MHz single core

But the best feature about this phone was the sliding backlit qwerty keyboard. 👌🏻
