BrowesrInApp is a new tweak that basically installs an in-app browser into iOS. In case you are confused, applications like Twitter and Facebook have in-app browser, but Messages and Mail don`t. This tweak allows you to open a URL within an application without having to switch to Safari or your default browser.
Once you install the tweak, use it to open links in applications that don`t have an in-app browser. Opening an in-app link will load in a lightweight web browser that load over your current window. You will have an editable URL bar, a back and forward buttons. Easy to use interface and an option to open the link in Safari.
The tweak is a time saver. You won`t have to use Safari each time, It`s available on the BigBoss repo for $.99.
