Im at FW 1.1.4 unlocked with Ziphone. Everything works.
Why would I want to upgrade to FW 2.x?
1. maybe because I want the cool search feature in my contacts, but, I already have contact search PLUS calendar search.
2. maybe because FW 2.x runs faster, not from what I see posted..
What is your reason for going to FW 2.0 on an already working unlocked gen1 iPhone on FW 1.1.4?
