Here is the template for all my gloss iPhone app-style icons. Made and fully editable in Fireworks.

If you make these styles of icons please use parameters similar to the ones that I have used, or use this template as others are going to use this and it allows for consistency.

I leave a 1px gap between original and reflection, white path has opacity 36% rounded rectangle is linear gradient of solid colour from 100% opacity at the top to 80% at the bottom.

I will be posting a tutorial on how to make these and how to create a logo from this template in the near future.
