i have just download application from itunes through my pc and the application was done but the problem is that when i sync my iphone i cant sync the application, i cant click the sync option to sync all my application. is this because of im using a JB phone?

ok done...

but my newest problem is where my topup was taken without im noticing it, do i need to change anything just to remind me if the phone was connecting through internet? or because of im downloading files at apps store at wifi place, after that i just disabling my wifi because of i got to do other thing at other place... is there any solutions?

iphone noobie!!~
