Not seen a post of yours since the Touch HD release
Mine has that gap at the top where the screen meets the casing - its not bothered me until now and the pocket dust is building up. I'll check the white hero tomorrow and see the difference, if so different I will return the device as I am still within the 7 days as I received my device last wednesday.
I'll post an image tomorrow when back in the office.
Why freeload? If you like what you use here, donator to the DEV, Themer or the XDA Community.
