Oh, been a while since I had those as my homescreens. But I did make a thread about it over at xda, so here you go: [ICONS] Android Phone 7++ - xda-developers
You can also get the files and view the original idea here: [Layout] Android Phone 7 (HDPI) - xda-developers
The tiles made by X2K2 are also excellent: [ICONS] X2K2's Tiles Icons (220) (Designed For 800x480) [V4.1 - 11|16|2010] - xda-developers
(Note: these tiles aren't compatible with mine or the newone757's as there're significant size differences.)
Enjoy! If you need help setting all this up, PM me.
