It will be frustrating if a LG KU 990 is bought online and the phone comes with no installation CD or stylus. A stylus and a USB cable come by default with the KU990 but it is important to note that its lighter version i.e. KU990i does not come with these accessories. As far as the missing installation CD is concerned, the user can still download the requisite software program either through a direct link available online, or from the product website. On the LG site, one can get the link from Manuals & Software Downloads under the Product tab. To install this program, PC sync has to be done through the proper process. Settings in the connectivity tab of the phone should be checked so that the phone can be easily recognized by the PC. Telephony revolutions have arrived and one should reap the benefits from it.
