You won't get PC Suit software for any Samsung handsets (including galaxy pocket). The software is called as Samsung Kies and you can download it free of cost from this link: http://www.samsung.com/in/support/usefulsoftware/KIES/JSP
Using the KIES, you can connect your phone to PC and manage the folders and files. Even you can sync your contents of the phone to the PC via Wi-Fi, which is completely automatic. You can also update your software versions by using this software.
You can also download the Samsung New PC Studio software (which may be came before the Kies released) from this link: http://downloadcenter.samsung.com/content/SW/200910/20091019103134468/New_PC_Studio_18.104.22.16864_2.exe
