Ok I flashed JJ1 eboot and phone to my i8000L. Previously I was using JI1 eboot and IJ1 phone. I also have CSC I8000LBMCIJ6, and PDA I8000NXXJI1.
Here is my speed test when I am tethered to my PC:
Download: 4.49 megabits/second
Upload: 2.70 mebabits/second
Download: 5.05 megabits/second
Upload: 1.40 mebabits/second
I tested a few more times, and i find that download fluctuates between 2-4mb, upload 1-2.5mb, and ping from 80-110.
I should have done more testing before, only tested once.
Also wanted to add, my GPS lock times are still very good, 15-30 seconds indoors.
