Case-Tough, yet fits in speaker

Hi all,

I am looking for a fairly tough case (one that can survive falls without damaging the iPhone too much).

I have an iPhone 3GS and am looking for a case.

I have a couple of speakers and do not want to take off the case constantly.

Any suggestions would be nice...

Speck cases

I am not sure where you are located, but Speck cases are the best, and all ports are accessible. Apple stores have them in most countries, check out this case, I have it and it is excellent
