I found out the right way to fix the issue where-in you don't get any signals on t-mobile (or any other GSM carrier) once you upgrade to firmware 2.0 and then downgrade back to 1.1.4...the detailed instructions are at : iPhone (1G) Downgrading 2.0 to 1.1.4

I was finally able to jailbreak, unlock my 1st gen iPhone on 2.0.2. If you unlokced your phone using Ziphone, like I did, any upgrades using iTunes will leave your phone locked. The best way is to use the new WinPwn 2.5 just released today!!!!!!
