Default Hard battery case for wifes new t989 ?

Just bought the wife a t989 and a powerskin battery case to go with it . I dont like it . It has a flimsy charge cord socket and the microphone keeps getting covered up during a call .

Are there any hard battery cases out there for this phone ?

I have a samsung power pack for my vibrant and love it. I was hoping there was something similar out there for her phone.

Thank you
