I guess this will be pretty simple for all the expert here.
I dloaded quite a number of APPS (say A,B,C) directly from APPS store through ipad WIFI connections.
At the same time, I also dloaded few APPS (say D,E) through my PC.
Now, how can I sync those APPS (D,E) dloaded from my PC to my ipad without deleting those (A,B,C) dloaded through ipad wifi ??
