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 Iâ€™ll not get any support in India. PLEASE ADVICE!!
