The sleep function on my original holster stopped working. Been looking all over a good holster, outside of the original one, that supports sleep mode and is generally a good holtser.

Anyone have any models in particular they really like and could reccommend?

Bout your only option.

I use this holster: go to this site, bberry.com/content/accessories/4-25--690.htm

I have been using it for almost two weeks and really enjoy it. It is leather and has the sleep magnets you are looking for.

I use the same one. Good tight fit, well built, nice clip.

I would guess most Blackberry dealers would have them in stock.
