If the more button in SBSettings opens and then crashes immediately, you may be able to solve it… The author posted about the issue on his blog. He had this to say:
” If you are on 3.0… It’s not a problem with sbsettings. It’s in your jailbreak. To properly make it work on 3.0 beta, you require a private, not yet released kernel patch and to fix your crashing on loading the more app, you need to install the package that includes dirname. (It will be installed on a real 3.0 release build). Look for one of the *-cmds packages like “adv-cmds”, “file-cmds”, “shell-cmds” or just install all 3.”
The author was talking about the 3.0 Beta, however. Which didn’t explain why this was happening on my official 3.0.
Some other users also report that installing Core Utilities and system-cmds fixes the problem.
Personally, none of these things fixed the problem on my 3.0 (non-beta) iPhone 3G. (perhaps something left over from a restore) I ended up re-jailbreaking – installed the newest version of SBSettings, (which now also installs some of those cmds) and it works great. I’ve had up to 51mb of ram available.
Anyone run into this and solve it without jailbreaking again?
