Upgrading to 2.1
I have an old 4gb iPhone and I want to upgrade to 2.1 because 2.0.1 has been absolutely horrible. I used pwnage tools previously and I'm not sure if I should be following the same steps are before to upgrade to 2.1.
All the guides I found on modmyi pertain to 3G phones, has anyone else upgrades from 2.0 to 2.1 with an older phone? If so what guide did you use or what steps should I follow?
I believe I used this guide to upgrade to 2.0. Would 2.1 be the same but just with a different ipsw file?
Thanks for your help in advance.
