Thread: WARNING - MobileSubstrate blocks 3G connection on iPhone 4

    Default WARNING - MobileSubstrate blocks 3G connection on iPhone 4
    Alright, im texting from my phone, so ill keep it short.

    It seems that MobileSubstrate (used in Cydia) blocks any mobile data connection, except for WiFi. I found this out when I was installing SBsettings. It updates MobileSubstrate as well, and the i4 dont like that.

    So until there's a fix for this, don't update MobileSubstrate!

    Running on iPhone 4 - iOS 4.0.1 jailbroken using JailbreakMe

    It works fine for me with sbsettings, is the 3G toggle turned off?

    Works fine for me too. Toggled WiFi on and off - 3G worked just as it should.

    Tried reset network settings - but nothing
    I don't want to uninstall mobilesubstrate just revert back to older version - is this possible?
    So annoying - I just installed the update because I thought it would fix the Skype multitasking issues, but that does not work either

    Yep updated this morning and 3G is gone. Running iPhone 4 on 4.0.1. I'm stuck with only edge.

    UPDATE: I reset network settings and still nothing, then after about 5-10 mins of just letting it sit 3G came back on. I think there is a slight glitch or delay in some of the programing.
