    I used to jailbreak first gen iPhone's for T-Mobile with no problem. I just got a 3G[S] and I need to jailbreak it for the same purpose.


    It currently has 4.3.5 and I want to downgrade to 4.2.1. How can I do this?

    I've already searched extensively.

    Without SHSH blobs no downgrades are possible.

    Currently, Apple is authorizing iOS 4.1. This (or the latest 4.3.5) are your only iOS options.

    Because 4.3.5 is currently installed, unlocking for T-Mobile requires upgrading to the iPad 6.15 baseband which also breaks your GPS. Not the best unlock solution, but the only one available.

    I'm stuck in restore mode, and it says I am not eligible for 4.1 or 4.3.5 now. What do you suggest I try next?
