Samsung Galaxy S2 comes with amazing connectivity options. It does support 3G data speeds up to 21 Mbps (HSPA + networks), Bluetooth 3.0+HS transfer, Wifi Direct, Allshare (DLNA) and HDMI through MHL.
Unlike Apple iOS, where you can’t even transfer the pictures taken with the camera through bluetooth, there is no restriction here. You can transfer files through highspeed Bluetooh (it is the only device at present that supports true 3.0+HS standard), or Wifi Direct. Using Allshare, you will be able to stream multimedia content wirelessly to any device that supports DLNA (you can use XBMC media center software in your computer as well). Kies Air enables you to manage the phone content wirelessly without any software or driver. It also supports Usb on-the-go so that you can connect other USB storage devices directly to the phone.
