Still can't purchase itunes from your iphone?
No account information found. Please connect to itunes to configure your account.
Have you tried all the other suggestions and are still having trouble?
Heres what worked for me
and I tried many suggestions.
1) Make sure that your iphone is backed up so that you can restore from this backup. Youll be asked to do this later, but save everything such as your music first!
2) Sync with your iphone (if its not detected, thats another problem). Then disconnect iphone.
3) Restart both your computer and reset (sleep+home buttons until apple shows) your iphone.
4) Open itunes and sign into your account (make sure you have a valid credit card, etc.)
5) Go to your iphone setting by clicking on your iphone under the left panel DEVICES.

11) At the next prompt, click Restore.
12) Choose the option Restore from the Back Up of:
13) It will take a long time to do this; mine took 10-20 minutes. Once its done, repeat steps 4-6.
Once I tried to purchase again, I saw a little animation take place and a 1 jumped onto the downloads icon. Hooray! I hope it works out for you too.
