iPhone app store login and password

ok here goes.. i was using my gmail address as my itunes and iphone app store login and it has/had a password. ok.

so then i changed my login to my me.com email address (in both itunes and on the phone) and using the password for my me.com account.

i went into account setting in itunes and changed everything there.

i went into settings on the phone changed it there.

but yet when i go to the iphone app store on the homepage of the phone it still ask for m gmail login and password. if i try to put in my me.com password it says wrong password.

i have verified that EVERYTHING in itunes and the phone is using the me.com login etc.. i have signed in and out everything and resigned in .. still when i go to the app store from the home page i has the gmail login and needs the gmail password..

not a problem but kinda of a hassel cuz i want it to all be on me.com

using iphone 4 with most up to date software
