Review: Samsung Focus S for AT&T
The Samsung Focus S has the same, simple set of communications tools found on other Mango phones.
The email app supports Microsoft Exchange as well as POP and IMAP email accounts. Gmail works really well in Mango, and thanks to the Exchange support built into Gmail, you can add Google Calendar and Google Contacts as easily to the Focus S as you can Gmail itself.
The SMS/MMS application offers threaded conversations. Text appears in colored bubbles in a way that will be familiar and intuitive to most people.
As for instant messaging, the only client built into the OS is for Windows Live and Facebook. For all other IM services, you'll have to seek out third-party apps from the Marketplace.
The People Hub serves as your nerve center for social networking. It provides a rich, well-rounded social networking experience that includes Facebook, Twitter, and Linked In.
In addition to the People Hub, Twitter and Facebook both offer full apps built for Mango available in the Marketplace.
