Hi,
I successfully downgraded from 3.1 to 3.0 using Sauriks method. On Friday, I had used the Dev Team's Pwnage Tool to upgrade my 3GS to 3.1, but the battery was completely draining in a couple hours. I downgraded to 3.0 using the file that was being held on Cydia. It was very simple. So I downgraded to 3.0 and everything works great but the battery is still draining quickly. Why is this happening. Like I said it's a 32 GB 3GS. with firmware 04.26.08 and running 3.0. I have absolutely no apps installed except Cydia. And yet the battery problem is not solved. Any ideas would be greatly appreciated.
