Q: I can't buy extra storage space for my iCloud account..

Same problem here!! I just keep getting the error after i tried to buy extra storage. (an unknown error has occurred)

same here.  unkwnown error has occurred..

Add me to the list too. But my message says that my email address is not valid. My email address has been verified and I signed in with it. Weird.

Me too. Same issue. Tried it on every device I have.

Zero luck.

Same problem here.. Contacted iTunes support, but they couldn't help me, called Apple here in my country closed.. Not to pleased with this.. :/

Does Apple reed these support forums by the way?

i have the same problem.. i use Apple ID credits instead of a credit card, and am wondering if that is the issue (should not be). are you using credit card or gift cards?

i can still do other purchases on Itunes, except for the storage space - so my account is valid and working.

I am also on Mac OS X Lion 10.7.2 and on IOS 5 on my ipad and iphone, so Apple has no excuses to send me an "unknown error" messages...

Exact same problem. I'm using pre-paid vouchers. Are you?

ooooh, oooooh you can add me to the list also ??????

I have been trying to solve this problem for last 3days , still no luck , same message an unknow error ....

contacted apple ,no clear answer they said may be because your account with no credit card ? try to open another one with credit card ???????

Apple should look in this soon .

I guess the problem is getting a little bit more clear to me.

My guess is that we all use iTunes giftcards (as some of you already said)

and no credit card linked to our accounts.

So this could be the problem that we all are getting the unkown error issue.

But then again, as we all can read in the terms and conditions of iCloud, it says that a valid credit card is needed for purchasing extra storage for iCloud, "AND" as well is itunes store credit a legit way of purchasing extra storage for iCloud.

So my guess is, they would accept iTunes store credit, but only when you would have a credit card linked into your account.

I hope this isn't true and it is just another problem, but it all points in this direction.

That would be a big fail.

same problem here, in my itunes credit is $99.00 but when I try to purchase the icloud storage same problem occur "An unknown error has occured"

Sorry but I have the exact same problem and yet I am using a credit card (the one attached to my Apple ID, with which I have no problem to buy music or apps from iTunes)... Can someone tell if there is a solution or at least if someone else has the same problem that I have (i.e. impossibility to increase icloud storage although not using prepaid cards ???)

thanks!

YES I am having the same problem using a credit card. In fact I have tried two of my credit cards and none of them worked on my iPhone 4, iPad 2, and MacBook Pro when trying to upgrade storage. It usually says "your email addres has changed or is invalid" and mixed in it sometimes it says "the iTunes store is unable to process purchases at this time/credit card processing is temporarily unavailable" but this is a crock because I've purchased plenty of apps on both mobile devices, a few songs on each, and rented movies all on my credit card hooked up to my Apple ID/iTunes account. I don't understand why it works on everything but iCloud storage upgrades at a time when it seems most profitable. I hope they solve this issue quick, I can barely back up my iPhone, let alone iPad, computer files, media, and mail. APPLE FIX THIS QUICK!!

I have the same problem. Do any one know any way of getting in touch with the iCloud support team?? I only get a message that My email addres has changed or is invalid.

Please Apple fix it!!!
