If you are accessing certain websites very often with your Android powered Samsung Galaxy S2, I suggest you to add a bookmark shortcut to your phones Home screen.
Let me show you how to set up a Wi-Fi hotspot on Nokia Lumia 920 and other Windows Phone 8 devices so you can share the Internet to other Wi-Fi enabled devices.
Bookmarks are a great way to save the website addresses you don't want to forget about, this is how you add them to a stock web browser on your Samsung Galaxy S2.
If you are on a certain data plan on your mobile provider, and don't want to exceed it, you can set data usage warning and a limit which can help you save some of your money.
