No, I don't think it would fit.
- First, iPhone's edges are more tapering and rounded, if you know what I mean. HD' edges are thicker.
- The opening for camera for iPhone at the back is at the top corner, whereas, HD's is in the top centre.
- The headphone jack of iPhone is about 10mm more towards the edge than HD's
- HD needs an opening for the stylus in the place whre iPhone cases has no opening for.
- iPhone's bottom has a large opening for its cable, and this hole would be considered too large for HD.
Hope this helps.
