Q: All my Apple can't connect to iTunes Store... Can you help me please. Thank you so much.

As these are public forums (you're not talking to iTunes Support here) I've asked the hosts to remove your email address from your post (posting it is an invitation to receive spam).

There are problems with the store that are affecting a number of users : http://www.apple.com/support/systemstatus/

As I'm a fellow user I don't know when it might be fixed, but you could check that page occasionally to see when it's back up.

If you are asking about how to fix the problem with the store then I assume that as they are aware of the problem then Apple are working on a fix - I don't know how long it will take before it's working again, but check that status page occasionally and when it changes to green then the store should be working again

Posting an email address on a public forum (especially forums that a lot of people see) is generally not a good idea, it can result in spam being sent to you. The hosts have now removed it.

You can change the email address on your account, but you don't have to - not many people may have seen it. If you want to change it then you can do so via http://appleid.apple.com

According to the status page the store should now be working
