I am wondering about this myself since classes are starting up again. I have done the .215 patch, fdr, battery cycle. Now am probably going to root but want to know what to do after mainly for battery, but also just general better phone performance. I have read some of the other posts about what to do like MattyP's what he did to his phone (under clocking in-particular) and the list of okay stuff to freeze (links to these would be great since i forgot to bookmark them and can't track them down) but wondering what else to do. And is titanium backup really the only thing needed for these tasks.
Thanks
I use SetCPU to underclock ... I think it's a couple bucks in the Store. I use TB to backup all my apps, and to freeze apps. I think it's like 5 bucks, but worth every single penny.
