    Default [2.0.1][PwnageTool] Is the instability PwnageTool's fault or the firmware's?

    I'm finding firmware version 2.0 to be much less stable than 1.1.4. But I'm experiencing a reset/kernel panic a day, for example while I was running the Bloomberg app today. I never experienced resets under 1.1.4!

    Are others seeing this much instability? Is this a result of the kernel patching by PwnageTool, or is it just a buggy OS?

    Neither. Uninstall Cydia and your phone will be stable and fast. Trust me on this, I did it myself and the difference has to be seen to be believed. I wish Pwnage had an option like iliberty did to not install it or at least fully remove it after it does it's thing.

    I had come to the same conclusion as you about Cydia (who really needs it now?), and last night I rebuilt the firmware package without Cydia (Pwnage does offer this feature if you choose "expert mode") and then restored it. Nevertheless, I had the kernel panic today while running Bloomberg. I'm not experiencing performance issues, but rather stability issues.

    By the way, it isn't enough just to uninstall Cydia: the developer told me that it patches all sorts of libraries and frameworks (but "very safely," he says). If you really want to remove it, you have to build a custom firmware package without it (via "expert mode") and restore that.

    If you noticed this, it was most probably the placebo effect. One of my phones is perfectly legitimate (no pwnage or anything, only app store apps) and I get all the same kernel panicks, random application crashes, and chunky movement. It's a known issue about the released 2.0 firmware, and there have been many complaints by other legitimate customers.

    I know you think we're all crazy, but there IS a difference in speed and flow between Cydia and *no* Cydia on a PWNED phone. I don't have a legit phone to compare with, but I'm also not experiencing any crashes or kernel panics.

    All Cydia does is sit in the applications folder. If it's closed, there can be no side-effects of its presence. Cydia applies no patches of its own to the system, so as I said, there's no way this can be happening.

    I really wish I could easily show you what I was experiencing. When I tapped "Settings" it would open and show the background, but none of the actual settings would show for about 10 seconds. Now, it happens immediately. The same thing with SMS. I'm no software expert, but I suppose it could have been corrupted software or a bad restore. I thought Cydia installed it's own "BSD Subsystem", or does it not?

    pumpkin -

    I'm pretty sure that Cydia moves all of the applications (and possibly other stuff) from the root file system to /var/stash (second filesystem). Right?

    Are either or both of these filesystems compressed and/or encrypted (and therefore possibly slower than the other)? Maybe the apps being pulled from a slower partition is the cause?

    Just a completely wild guess. (and I'm just curious).

    Thanks,

    - Paulb

    Also Cydia has it's own equivalent of "BSD Subsystem" which installs along with Cydia. These utilities might be causing some of the issues.

    How great that an iPhone dev member is posting here! Thanks for your wonderful work so far!

    Thanks for corroborating the system instability problem. However, I don't think it's true that Cydia doesn't apply any patches of its own. Jay Freeman, the author of Cydia, admitted that he does replace some of the core libraries on the phone. He adds, however, that he has done this in a very safe way.
