iPad safari - certain links not responding

Hi,

I've had my iPad since launch week, and have never had any problems with it. It is jailbroken, running 3.2. However, today, safari has been acting up. I first noticed that certain links on the Tumblr dashboard weren't working, namely text entry, photo entry, and quote (I think). Then when searching for a solution on Google, I noticed that some links there wouldn't work, especially the sub-pages. Sometimes it would be fixed by zooming in (although, I don't know if I'm imagining it, but that seemed a bit laggy too), but sometimes it wouldn't. The bar at the top of my Wordpress page didn't respond either, unless it was the buttons on the far right.

I've tried:
Restarting the iPad
Turning the iPad off, leaving it, turning it back on
Resetting network settings
Deleting cache, cookies, history

I really don't want to have to restore my iPad, as I'm a bit unsure as to how to keep my jailbreak. I have my SHSH blobs backed up in Cydia, but I don't know how to use them.

Thank you for any help!

EDIT: Problem has disappeared. Weird.
