you can't switch from a basic account to a savings account. Nor can you originally select a savings account. The link to select a savings account is not functional. It wasn't functional in the first version, and it still isn't functional in v2. since the link is non-functional, nobody is able to access a savings account, thus-forth giving us all basic accounts. Savings accounts probably will not be added to this site for quite a while.
hope this helped you!
