    okay it gets more confused as i read more and more threads about this...so i decided to ask.

    currently my iphone 3G has been JB'd and Unlocked at 3.0.1 firmware(T-mobile).
    since i have no mms and battery drain problem(not strong but yea i have).
    i have jb'd it via redsn0w on windows xp. if i required mac to upgrade the firmware i can easily go to computer lab in the school and get mac to do it.
    so my questions are:
    1.) 3.1.2 fixed the battery problem???
    2.) i only have winterboard and cydia and bunch of apps from apple appstore
    will i lost any of them?
    3.) after upgrade do i need to unlocked the phone again with ultrasn0w?
    4.) i dont need to worry about baseband right?
    5.) what else i will get besides mms?
    6.) how to do it?

    When you build the custom restore IPSW, make sure you check activate phone as I believe you use T-mobile, Use expert mode, 3G is phone icon on the far right (also it's for 3GS), only include Cydia, OpenSSH and OpenSSL, not Icy, in your IPSW (nothing else), WHen asked if pwned before say no.

    Since you have a 3G I strongly recommend you restore to official Apple 3.0 firmware and choose set up as new phone to get rid of all JB issues, then use PT to build your IPSW then use iTunes to install it.

    Make sure and option + click update and choose the custom IPSW not the Official IPSW or you will lock your phone.

    I think dhlizard's instructions are only for if you have a mac. If you have a pc then it's shift+restore (or shift + update... this means hold down the shift key and click update, this will give you the option to select your firmware). Custom firmwares can only be made with macs, so you'd have to get a friend to make it for you, or there's a thread on here somewhere with a link to a whole bunch of custom ISPWs that you could use.

    And YES you do need to worry about the baseband. Do not update it or you cannot unlock.

    Option + update lets you browse for an IPSW. If you just click update, you can't browse.

    You only need to make a custom IPSW for the JB when you are ready (PT and it requires a Mac)

    Download the official Apple 3.0 IPSW (Use google to find it, get it from a reputable site) Here is a guide, there are many others, Use google

    Also, as a hint to you, save all these official Apple IPSW's and those you make with PT as you never know when you might need them again. Just store them in your documents folder or wherever.

    Here's the thread with the custom IPSW's http://forums.macrumors.com/showthread.php?t=803052 .. as of right now, this is the only way for Windows users to keep their phones unlocked if they want to update to 3.1.

    Btw, I'm still on 3.0 and I also have T-Mobile and I have mms. You mentioned you don't have this yet, but you don't need 3.1 to get it.

    I always wait a long time to upgrade to see if there are any bugs I want to avoid dealing with. Like 3.1. SO glad I didn't rush that one. Everything is fine for me on 3.0, plus it's such a pain in the ass to re-organize all my stuff / apps / cydia apps.

    how long do you usually wait to see if theres any problem with newer firmwares?
    is this mms thing original as apple apps or something that you have to hacked?
    im about to go ahead do upgrade to 3.1.2 in 3 days,,, y'kno just wait and think more about it and do it hope there is no significant error with 3.1.2

    MMS is official with AT&T since Sept 25th

    The biggest JB issue with 3.1 and 3.1.2 is excessive battery drop.

    If you get it, you have to restore to official Apple IPSW, then re-JB.

    To avoid issues like this always choose set up as new.

    A couple months I guess is my average. Or when apps start requiring that I upgrade if I want to use them, whichever comes first. It's official mms, you just have to enter the information in your network data for it to work (same goes for 3.1.2.. it doesn't just magically start working).

    No offense to dhlizard, but don't follow his advice or you'll end up with a locked phone. ;) I don't know if he's realizing you're with T-Mobile.

    I've heard conflicting reports on battery life on 3.1.2. I think most said it improved, but maybe for jailbroken phones this isn't the case. :confused:

    I'm pretty sure he stated in another thread his SHSH is on file in Cydia, so he can go back to 3.0.

    He knows not to go to Official Apple 3.1 or 3.1.2

    Jailbroken 3.0 firmware questions

    I have a Tmobile jailbroken phone I bought from a second party I have a few questions.

    my phone has resorted back to original owner name, so I am unable to move my music from itunes to my phone. However I am able to download apps it still recognizes my login info. How do I remove old owner name and get mine back on there?

    Should I update to 3.1.2 Firmware or will it reset my phone?

    Thank you in advance for any help you can provide.

    I thought you were previously JB and did this SHSH capture with Cydia.

    Do not upgrade without these, as you cannot downgrade.

    Here is some info http://www.saurik.com/id/12
