So I know this is not a topic that I should be asking and im sure im going to get some flames for it, however im going to ask anyway. Right now im running androiid 2.2 on my phone with the bugless beast custom rom. However I despise 2.2 because it makes my phone very sluggish no matter what I do, even with the custom rom and even overclocking. My question is how would I rollback to 2.1?? Would I just use rsd lite? Do I need to go back to stock 2.2? can I just use sb recovery and install a 2.1 rom? Im not exactly sure how I would go about going back to 2.1, any help would be appreciated.
