Download MobileSubstrate 0.9.3995 To Fix Cydia Tweak Errors On iOS 5.0.1 Untethered Jailbreak

Today we told you that the iPhone Dev-Team released a new version of RedSn0w, dubbed RedSn0w 0.9.10b3. In this new version of RedSn0w comes an update to MobileSubstrate (an essential Cydia tweak dependency) that fixes errors while using and installing Cydia tweaks to your iPhone, iPod Touch and iPad. In case you do not want to have to re-run RedSn0w o.9.10b3 over your existing Jailbreak, Saurik (creator of Cydia) has pushed an update through Cydia for MobileSubstrate; this brings MobileSubstrate to version 0.9.3995. In MobileSubstrate 0.9.3955 you should no longer have issues with Cydia tweaks, while Jailbroken untethered on the iOS 5.0.1 firmware.

In order to download and install MobileSubstrate 0.9.3995 you simply need to launch Cydia, go into the Changes tab and refresh your sources. You should notice an update becomes available and then simply install MobileSubstrate 0.9.3995 to your iPhone, iPod Touch or iPad.

    Send an email to Saurik. You can do that by going into Cydia, searching for Mobile Substrate and then tapping on Author to send him an email describing your issue. It’s important to send this email from inside Cydia because it will automatically include all relevant data like your phone and OS version and crash logs.
