3G: Do all silicone cases stretch?

[Sonoran]

I have a SwitchEasy and really do like it. Adjusting the volume & other controls is great. However, I put my 3G in my front pocket all the time & the case has stretched out a lot.

Do all silicone cases stretch after a while?

Can someone recommend a hard case that has the same "sticky" grip of a silicone case?

The iSkin solo, or the polymer cases that can be found on my site (not trying to advertise...it's an answer to the question). They have the slick outside feel of a hard shell but are still soft to the touch for buttons and grip.

not all silicone cases do,
i have the capdase soft frame and the incase protective cover, neither of them stretchable.
