This is my boss' iPhone... He is using 2G iPhone, and wanted to change to 3GS... He wants all the data to be backed up so all information in his current iPhone can be stored in his new 3GS...

the problem is, when i sync, there's no backup data in the folder, iTunes option is lesser than mine (i use 3GS) and i can see my data...

i would like to seek assistance from sifus here as i am unable to solve this issue...
