Back to Top Contact is a tweak to automatically scroll the Favourite, Recent and Contact tables up to the top when launching the Phone app. It is useful if you have a lot of contacts. You don't need to tap on the statusbar anymore to scroll your list of phone contacts to the top.
There is no icon after installation; just configure the options in the Settings panel (you can choose to active the tweak upon the Phone app launch and/or when swapping between tabs in the Phone app).
Works for iOS 3 and 4.
