Just to clarify wireless N since there's some misinformation in this thread. Unless your internet speeds are higher than 54mbps, this will not let you browse/download/upload to YouTube faster.
If you have a wireless N router, this will let you transfer files faster between computers on your network, theoretically. I say theoretically because as of now, all file transfers to and from your iphone have to be done through itunes, through a usb cable, making wireless N pretty useless on an iDevice.
I did read about an app that will allow wireless syncing through itunes tho? In this case it should come in handy. In general tho, wireless N on phones (include android) is something that looks good on paper, but kinda meh in practice. Your max storage on your phone is going to be between 8-32gb so you can't really transfer large files. N shines when you're streaming 15gb HD files from your server to your media player tho
Actually, it sounds like you are confusing mega
bits per second (mbps or Mbps) and mega
bytes per second (MBps). Big difference. In data transfer, mega
bits are the unit of measurement. There are 8 bits in 1 byte, so 1 mbps = 0.125 MBps. For WiFi connections, 802.11g maxes out at 54 mbps (megabits/sec),
which equals 6.75 MBps (megabytes/sec). 802.11n tops out at 540 mbps, or 67.5 MBps. This is a very real difference and one that does pose a browsing problem as broadband connections commonly exceed 6.75 MBps download speeds. Comcast, for example, starts at 12 MBps and sells upgraded packages of 16 MBps and 22 MBps. Granted real world connections are rarely as fast as advertised, exceeding 6.75 MBps is not out of the ordinary for broadband connections.
