Saya mau tau BlackBerry Internet Service dari BlackBerry. Jelaskan dalam bahasa melayu

The primary alternative to using BlackBerry Enterprise Server is to use the BlackBerry Internet Service. It was developed primarily for the average consumer rather than for the business consumer. This service allows POP3 and IMAP email integration for the personal user. It allows up to 10 email accounts to be accessed, including many popular email accounts such as Gmail, Hotmail, Yahoo and AOL. There are also special bundles for just Myspace, Facebook, & MSN as well.
