Invalid Address Tap Continue to sign in...just poped up on my iphone this is the solution

this is probably another security feature apple just added I've surfed the web for a little bit and there u go..


I had this endless "invalid address" problem, and I wound up fixing it for me.  Here is what worked for me...

1. Remember that there are not actually three, not just two, places that your billing address and credit card information are edited in the Apple Store world. (1) The website http://store.apple.com... (2) the music store that you access from your copy of iTunes that runs on a computer... and (3) the Settings->Store configuration on your iPhone or Ipod touch (and I guess on your iPad)

2. For me, the problem was originally caused because I had actually gone and CHANGED my billing address over at location number 1 mentioned above, the apple store website, because I wanted them to bill an iPad purchase to a specific credit card. That wound up creating some kind of confusion somehow within those three systems.

3.  So, what worked to fix the problem for me:

• I first closed out of all three of those locations that I mention above (web store, iTunes store, and ipod touch config screen. 
• Then, I went to the very first one I list above, the website of the apple store, and I totally reset my credit card and billing address back to a specific credit card I have (namely, the one that I used when I first ordered an iPod purchase that is in fact still waiting to be shipped.)
• When I hit submit on that apple store website credit card screen, it nicely did a little online confirmation of my credit card/billing info.
• Then, I went to the second location, the copy of iTunes on my computer and went to the iTunes Store entry for that, and clicked on my account (i.e. my email address that is up in the upper right corner.)  I saw that this screen nicely reflected the totally new address that I had just entered over on the apple store website. Then, I don't think I changed a thing here in the iTunes config screen, just clicked back out of it.
• Last, I went to the third location, my iPod Touch, and I went to do the operation that had been causing the "Invalid Address" errors (in my case, updating some apps.)   This time, of course, it gave me the same error, because it needs me to "confirm" the changes that I just made elsewhere in apple's system.  So it brought up that same **** address screen.  This screen also happily showed the new info I had set elsewhere in apple's billing system. SO, I went and entered the three-digit security code from the credit card in its place on this screen, and hit Submit.   The ipod thought for a bit, and then...
• Thank god, it actually started updating my darn apps!
