please help me with skyrocket!!

[dennador]

upgraded to ics with kies, which was only slightly frustrating, and I absolutely hate it. how do I revert back to my original OS? I am on a galaxy s2 skyrocket. I see also t; f postings for s2 but I don't know how much ch different mine is from that. is there a fast and easy way to go back to gingerbread? any help would be amazing. my phone keeps freezing, the icons are ugly, and the , scrolling is choppy. I have tried all other methods (factory reset too)
