I just got a BB 8820 (AT&T) two days ago. I am in need of a VERY good case.
I am a firefighter and own a landscaping business, so I'm probably gonna be hard on the phone. I've ordered ZAGG clear shield stuff, but want a case also. Need something affordable, secure, long lasting, and something that can fit on a 2" belt.
If you want true protection, then you should look at Otterbox cases. There are some in the 8820 case section, of that website and other blackberry cases as well.
