Thread: No 3G after downgrading 4.3.5 to 4.3.3

    Default No 3G after downgrading 4.3.5 to 4.3.3
    Well my 8 year old son had hit the "ok buttons" when I plugged my iPhone up, and it upgraded to 4.3.5 - my fault no question.

    I downgraded using TU to 4.3.3 and did the redsnow trick for getting error message 1. I've done it 3 times and still can't 3G working. I've decided the APN is wrong.

    I'm going to use that Unlockit - APN Changer for your iPhone website, but just to be sure, what is the correct APN for an iPhone on AT&T?

    Is this a 3GS or 4? Also, you said you used TU, thats confirming you have SHSHs for 4.3.3 correct? You used a stock 4.3.3 to restore to?
