Hello Guys. I am Amit from Mumbai, India. I presently use a windows based cellphone & a laptop. Recently I bought an 64gb 3g ipad from Singapore as it is not officially launched in India. I want to upgrade the ipad to IOS 4.2. Is it advisable to update the OS as if there are any glitches in the updation Iíll not get any support in India. PLEASE ADVICE!!
