How to fix some mysterious problems.

Just jailbroke my iPhone 4 (4.0.1 FW originally, now 4.2.1). Managed to get Cydia on the phone okay, but whenever I launch Cydia, the backlight starts strobing really quickly (I have kind of a headache right now, in fact). In addition, there's an image of Apple's logo and a progress bar; looks exactly like the one that shows up when you upgrade your firmware. Anybody else have this happen to them?

This is a really silly bug: we don't know what causes it (or how to fix it), and it makes your device go completely insane.

You can fix it with a reboot.

No good; even after reboot it happens whenever I launch Cydia.

Once you have Cydia all up to date (at least one reboot required) this should stop happening.
