Hello all, I am fairly new here, but I have been looking at posts from this site for about a year now. I have a problem were my App Store is broken and says I need to upgrade to 3.1.3, or it would say that "This App is Incompatible with this ipod touch: P2.requiredCapabilities.thisAppRequires". A while back when this was released, I read that it messed up my jailbreak. Now that it has been a few months, I wonder if it will be safe to upgrade. I have a 32 GB 3rd Gen iPod Touch, running with Tethered Blackra1n RC3. I use Winterboard quite often, with Cydia, Rock (Sometimes), Categories (SB), MXTube, mAdvLock, Backgrounder, and YourTube mostly. Will these Jailbroken Apps, along with my Jailbreak, still function okay with 3.1.3? Thank you.
