I'm from the UK. When I first used my phone I setup the Gmail account as it asks you for your account details when first launching the App. All is fine.
However, I have the same issue as mentioned above, and I only did this out of curiosity, but when you then go to the 'Manage App' settings for any of the 'google' stuff, whether it be 'GMail', 'Google Buzz', 'Google Mail', '' or whatever then at the bottim when you 'Show' it says 'Your Google Accounts - discover accounts/view configured accounts', you cannot tap on these options to actually view the settings, never mind change anything! It all seems a bit of a mystery to me how you are meant to edit these settings if, for instance, you change your password.
So, like the poster said, how do you actually alter your account details, as I 've never seen any option in the App Setup tools or the App itself which lets you change your GMail settings?
Like I said my phone is unlocked UK, build version 1.0.A.1.36
