I have downloaded the kindle app on my ipod and have registered, when I try and sign in it says "no internet connection please check your wifi or cellular connection"

My wifi connection is fine so I can't understand why it is doing this. I have tried and tried again but to no avial.
Help please!

Do you have any special characters in your amazon sign in name or password like '-' or '&' etc ? There are reports of people having problems with this.

No nothing like that at all?

Just updating my ipod, it is nearly done will try it again when thats finished.

It seems to be fine now. Must have been the update!
Thanks
