Thanks for the post and the link, very interesting. I know some of our TMO bretheren who have the TMO version of the 7100t would love it if you stocked the 7100 cases (all except the TMO version of course). There has been plenty of disgust with the current TMO version and I cant blame them I wouldnt want it. The current Cingular version (7100g) works well as I am sure the O2 and Vodaphone would also be big sellers.
I for one would buy two kits of the Cingular case so I can mod my sibling's 7100t
Seriously, I'll bet that there would be a good market for those.
