AlwaysArrange is a simple jailbreak tweak that allows you to easily rearrange your Home screen icons without having to enter wiggle mode. Once installed you can tap any icon and move it anywhere on your Home screen. There is a Settings mode that allows you to toggle AlwaysArrange on and off, and you can also adjust the duration of the tap and hold time that it takes to move an app. To delete an app just tap the icon and slide it up to the status bar to enter wiggle mode.
AlwaysArrange is available for free in Cydia via the ModMyi repo.
