    Hello All,

    I have been using my iPhone 3GS unlocked and jailbroken using Tmobile USA since July 2010 and it has been working perfectly fine so far until last week. I believe I accidentally connected it to my Macbook Pro and it started syncing with iTunes v9.2. Usually I charge my iPhone with a wall adapter. So far I do not think my iPhone had an automatic updates. My firmware version is still 3.1.3, Modem Firmware is still 05.12.01 and Carrier is Carrier 5.1. Ever since then I have been getting dropped calls for a week, and starting yesterday I have been getting the "No Service" or "Searching....." on the top left corner of my iPhone display. Cant make any phone calls or send txts out. I've researched enough and tried almost everything there is out there on the internet to fix this issue.

    So far, this is the following I have tried:
    1. Toggle between Airplane Mode
    2. Pull SIM Card out and place it in an old Tmobile phone to get service and then place it back in iPhone. This didn't work for my iPhone but I got a perfect reception on my old Tmobile phone which shows my SIM Card is working fine
    3. Reset the Network Settings
    4. Install Boss Prefs app from Cydia and do a full Reboot
    5. Restart the iPhone
    6. Toggle the 3G to enable and disable

    My WiFi is working perfectly fine. I do not know what was used to unlock and jailbreak this iPhone, because I bought it unlocked and jailbroken.

    I really do not wanna dispose off my iPhone, because I love it and I would like to troubleshoot it back to normal. Please help me out! I will highly appreciate it.

    Regards,

    Moe

    well you have two options.

    Call tmobile as they will help you with it, or go to the tmobile store.

    Or switch to at&t and not have a contract.

    Without knowing the jailbreak its gonna be hard to know how to do anything...

    possibility

    first make sure ur SHSH is backed up with Saurik on Cydia,,, then check dev team blog,, if you still have old bootrom you might be able to do a restore with pwnage 4.01

    @ njean777: Is there a way I can find out how I can find the jailbreak and/or unlck?


    @ jammaggic: What do you mean by SHSH acronym? Sorry I am new to this stuff! Also, how do I find out if I have the old bootrom?

    Thanks again for all your help!

    Just by your questions and responses this is gonna be very hard to accomplish on your own.
    Find someone local that is up to date with JB and unlocking iphones or start doing alot of research about the questions you're asking above.
