Asking for user verification in App Store?

Worked for me too. Yay!

Thanks!

I am having the same issue as well. Ever since I downloaded the new itunes to support the new ios4 hardware. I can't update any of my apps anymore.

I agree. It didn't happen to me until I upgraded to the new itunes to support the new IOS4 software and now I am in this endless loop and even when I put the CCV number in it goes back into the loop as if I never put the number in!

Thanks Valentine808, that worked for me too. It seems that my new iPhone was having a problem accepting that I'd changed the account associated with the phone. Logging out, and then logging back in again through the App Store went through my old account (and had old card details).

Pleased it's fixed for the time being - it was annoying the **** out of me having unupdated apps! - but Apple need a proper fix as I'm not sure I'm using my right account...

EDIT: the problem started btw when I upgraded from iPhone 3GS to iPhone 4 and first tried to update an app, not download music or anything (which I didn't try) if that helps anyone work out whether it's an iTunes or iPhone problem?

This may have been answered before but here goes. It is not a problem. Do not enter your security code on your iphone. Just log in to your itunes account on your Mac, click on edit and verify your 3 digit code here.
This is a secure connection, which may not be on your iphone.
I have done this and when I log in again to the app store on my phone, I updated and downloaded with no problem or verification.
Hope this helps

cheers valentine, that worked for me as well mate, top tip!

Thanks, this worked for me. Thank god the endless loop is over.

This worked for me as well. I think what is happening is that the apps I was attempting to update were purchased on an old account. Therefore, they needed the old account information to update. Once finished, I also signed out and signed in with my current iTunes account. This is the problem with switching accounts!

Is there a way to combine the two accounts? I think it has to do with the DRM rights. . . . Anybody else have ideas?

Thank you! Your suggestion worked. Thank you for saving me from the infinite loop.

this workaround worked for me as well. i realized halfway through the process i had been signed in on the old iPhone with a different iTunes account, but was trying to login on the new iPhone with my .me account. I signed out of everything on the iPhone (Settings > Store) and signed out of iTunes on the computer (just in case). it only looped twice after that 🙂

What if I don't remember the CCV number from my old credit card? It's been forever since I've had it.

I have found that they also charge a Euro each time to verify your card. My son spent 20 euros this week just logging in to the store on his ipod touch. I'd advise people to check their credit cards.

I am having the same problem and have been very frustrated with the "help" I have been getting...The problem seems to be stemming from having multiple accounts (my husband and I) which is completely confusing the i-tunes app program. What I finally did was delete those applications that needed updating, and went thru the app store and downloaded them as if I were obtaining them for the first time...No problem with that, and because it's using my most current info (my account vs my husbands) ti-tunes is not confused as to the user or account.

I've been having this issue since the 4.0.1 update.

It has nothing to do with credit ratings or refused payments. My registered card is cleared every month without fail, but for some reason I keep getting asked my card CCV number.

Never happened with my original iPhone, 3G or 3GS or the iPhone 4 until I updated iOS 4 to 4.0.1

It's a major pain in the ***

It's got to the stage I'm just not going to buy anything from iTunes until Apple get this bug fixed

Remember that you are being charged each time you login if you do so from an ipod touch. I seem to be able to login okay without a charge if I use a pc. I have found that I can login and browse the apps if I select (payment method none) on the ipod. If you enter your ccv number you will be charged for the check even if you don't buy anything.
