    Hey guys,

    I have a weird problem... I bought an iPhone 3GS off a guy on craigslist and it works great, no complaints. But every few minutes or so I get the alert saying that I "Cannot activate cellular data network - You are not subscribed to a cellular data service", and it's really annoying because it lights up my iPhone all the time and kills my battery. It's also really annoying - it comes up whenever I'm typing a message or playing a game; literally when I do ANYTHING on my phone. I do not have a data plan, but I have used 'unlockit.co.nz' to install a Fake APN to my iPhone to block data. Rogers has also given me a data block. This has been going on ever since I bought the phone, I thought installing a Fake APN would stop it but I guess not. I can't really restore since I have a lot of stuff on this iPhone already.. but if that's the only option then I will be forced to.

    I used to have an unlocked Fido 3G (about 2 months ago) without data and it never gave me this alert, do you think it has something to do with my 3GS being locked to Rogers?

    This phone is a jailbroken iPhone 3GS (model MC143C) running version 3.1.3 (7E18) and locked to the "Rogers 5.0" network. If it helps the modem firmware is 05.12.01.

    **If there are no real solutions, I still have 2 months left on my warranty. Would Apple fix it or give me a new one if I un-jailbreak it?

    Thanks in advance for your help!

    No idea how to fix that...

    Though buying a phone off some guy on Craigslist may not have been the best idea you've ever had. Just sayin'...

    iOS4 has an option to turn off data. So you should upgrade later today (err tomorrow depending on where you live)

    Plus Rogers will remove the data block on your account, as they will no longer be offering that service. Even if you did have a block on, they will remove it and will no longer be accepting requests to block data.

    You will need to restore it.
    Are you using it locked with a Rogers sim?
    If yes then just restore to the latest 3.1.3 and then use spirit to JB if you wish.
    Then install all your JB stuff again. Do not restore from backup from itunes.
    The problem might be restored back to the phone again. Setup as new phone.

    It's with a Rogers SIM, yes. I already have the latest 3.1.3 with the Spirit jailbreak... so wouldn't the problem just duplicate if I don't change anything? I will wait for iOS4 to come out though and then I'll see if the problem goes away. If not, I'll take it back to the Apple Store. Thanks guys!

    **EDIT: and I restored/set up the iPhone as new when I received it

    Sounds good.
    I believe with 4.0 beeing out tommorow and the option to disable carrier data on it you wont have a problem.
    Hope it works out.
