My wish list displays OK with 1.4.3. It took a few seconds to load, though, so I was getting worried, although I do have screen shots of my wish list that I made last night. Good timing, since the OTA update occurred last night. I only have 19 items, so if you have a lot more, there may be a problem.
As always, try a power down and reboot.
Well, I wasn't having any luck so I just waited and tonight my wish list returned. Go figure.
