The top handphone brands according to IDC are, in order:
Nokia, Cross, Samsung, Mito and Blackberry.
Nokia excels because of the hundred million or so rural dwellers for whom regular feature phones suffice. Blackberry has dominated the smartphone segment with its free BB message service. Now Blackberry phones have the Android operating system. There are at least 10 brands, including a number of local brands, using the Android operating system in Indonesia.
Cross and Mito are local brands of Chinese made phones. Samsung is making major gains.
Where is Apple? Presumably languishing without iTunes - see here. But plenty of people can be seen fiddling with iPhones in Jakarta elevators and malls.
