    That depends if you are staying on 3.1.3 or going back to 4.2.1.

    Going back to 4.2.1, I would have stayed on 3.1.3 based whited00r custom FW, but as stated before, none of the new apps run on iOS 3 anymore.
    I already made a custom 3.1.3 FW and I am currently jailbreaking it, what do I do after that?
    My guess is, open up 4.2.1 FW in sn0wbreeze and making it preserve the baseband and hacktivate?

    Ya, snowbreeze should do for that. No need to jailbreak 3.1.3 though. If you have issues with snowbreeze and a pre-hactivated custom firmware you can always make a non-hactivated one, restore to that, then jailbreak with redsnow to hactivate. I only say this because I think snowbreeze had issues with hactivating iPhone 3G firmware back on 4.2.1. At least some of the versions of it did.

    Just wanted to check if the 05.12.01 actually shows up in modem firmware section, and it does, everything really works.
    Alright, I'll try updating to 4.2.1 now.

    Also, can I use the default FW in redsn0w? It won't install the iPad baseband unless I tell it to, right?

    Yes, default firmware with redsnow. And correct, it wont touch your baseband unless you tell it to.

    It looks like the phone activated with SAM also, so that means I can now put in my SIM card and the push certificates will be fixed, and it won't waste cellular data anymore? Battery drain issues fixed?
    WOW, thanks a lot!
