The Glyde 2 IS the Reality... also known as the SCH-U960 (which is the Reality).
I think you may just have a regular old Glyde. It comes with a 2.5mm jack. The SCH-U940, which came out in May 2008.
She's right (of course)
There were 2 versions of the Glyde. (1.)
The Glyde & then Samsung put out (2.)
the Glyde Refresh, which was meant to replace all the Glydes that were f'd up (replaced mine twice).
When the Reality was "in development" it was being referred to as the Glyde 2.
