i have 2 accounts, 1 is indonesia which have my credit card info for easy apps purchasing, and the other is a US account which i need to buy music because the indonesian store doesn't have that. usually when im logged in with a US account in my iPhone, and there is a new update of some apps which i bought from indonesian store, i usually have to login with my indonesian's ID first in order to be able to update them. now with iOS 5 i dont need to logout from my US ID first, i just click update and then there's a pop up that's asking my indonesian password then i type it and it's starting to download right away. anyone else can confirm this? or is it available since 4.3.3? because im sure before that i have to login with my right ID to update them. this is really a life saver, thanks apple for sorting this out!
