Dear, after upgrading your iphone to higheor version, or any compatible version, Then after you do jailbreak, but after jailbreak also, to transfer games and applications, first we have to install app sync by particular version that i installed, like you installed 4.1 or 6 version, after that you have to add app sync 4.0 or 6.0 as particularly.
For source to add, just open cydia, then hacker , manage , then edit source and add this url given below, after installing this, come back one step .i.e return to cydia sources, after adding this source i.e. gsm doctor, then enter into it, and search for app sync for the software version you installed, and install it , after that you can transfer any data into the handset.
