Unknown error 5002.

I have seen the same thing. It gets real old real fast if updating numerous apps.

I'm seeing the same issue after updating my iTunes to 9.1

I just added a few iPad applications to my "Wish List" and now the error went away. Purchased a iPad game and no error. Very strange.

I'm having the same problem and it is so very aggravating!

I have tried all sorts of things I found on Google for past bouts of this problem. I have repaired permissions, re-entered all my account info, etc. Nothing works, it still gives me the 5002 for every single update item. It does download the update app but it either gives the 5002 or makes me enter my name and password about three times then forces me to the account management screen, where I can't find any problems in any of the options. I'm totally stumped and completely sick of it. Although I have had the problem of getting repeatedly and forcibly pushed to the account management screen in the past, it has eventually disappeared without me doing anything. This 5002 problem in addition is new though and all of it has occurred immediately after having updated to iTunes 9.1.

Ok and now the problem is back again. What gives??

I also have the 5002 error at every app, which is really annoying, so I just update straight from my iPhone.

I also have the playlist not syncing problem. This all happened since iTunes 9. The apps not updating since iTunes 9.1

Please fix this Apple! Love OS 4.0 lol 🙂

Sounds like i'll need to get over to my local Apple store to help everyone out. Hopefully there is a fix.

Thanks, because the nearest Apple Store by me is nearly 2 hours drive away. I really hope this can be fixed easily. Thanks JohnnyBoy628 🙂

having the same issues. hope a fix comes along!

I hate iTunes 9.1 a lot, I had so many issues since I updated to the latest version first it would not detect my PC as authorized and wanted me to authorize it again, second I would get an error not being able to sync the iphone properly and could not update with Outlook.

And last this stupid (5002) error every time I update an app.... So annoying and I wish they can release a fix really quickly.

Apple is taking the p!ss here, what is this rubish update, every thing is broken in iTunes.

Yeah, now it gives me an error when syncing that my iPhone cannot be synced. An unknown error occured. I try syncing again and it works. Fix iTunes 9.1!!!! I've been having problems since iTunes 8! All my friends have, too! We want iTunes 10 and iPhone 4G!!!! 🙂

Same problem here. I had downloaded the iBooks app although I don't have an iPad. Obviously I can't use it but I was wondering if that could be connected to the issue. I've removed it (iBooks) and waiting for more app updates to test it out. I've never had problems with iTunes and faithfully use Apple products but this update is Rubbish. (Probably a rush job for iPad compatibility)

I'm gonna through my hat in the ring too... still looking for a fix. The real thing that concerns me is the possibility of this small issue developing into something major.
