I paid £23 for this software which didn't work and tried calling and emailing them for technical support as I too accidentally upgraded to ver 2.0 and no one returned my messages, I've been waiting days...their site promises contact back in a maximum of 4 hours mmm. Don't waste your money, the site looks so convincing, I was so 😡!
I too have this problem and my iPhone 2G is now unusable, I upgraded iTunes to 7.7 then upgraded the firmware from 1.1.4 to 2.0 if anyone has any suggestions of how to get my phone up and running even only to use to access the internet and not make calls I would be extremely grateful. I bought mine unlocked and should have left well alone as I have no idea about these things. I was taken in by what I would be able to do with 2.0. Tried using ZiPhone software, but it won't recognise my phone. I tried restoring to previous firmware versions but just get the error code 20. I have downgraded iTunes to 7.5. Can anyone help please...?
