I will be getting a jailbroken an unlocked 2G iphone with 2.2.1 firmware soon. I read somewhere that firmware 3.0 is very slow. That said, I got some questions: - Is it worth installing? - Is it better than 2.2.1? - Can I install the jailbroken 3.0 beta on my 2G? - Will installing the jailbroken 3.0 render the unlocked feature on my phone useless? .
Last i heard about the firmware 3.0 was that if you installed in on your phone, you need to have a developers code to get it to work.
