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.
