Its is great phone maker in the history but its too much expensive as compare to its rivals like samsung, Htc, Microsoft, etc.apple’s iphone 4 ir 4s is too much short in its screen resoultion.and its also bad in its camera quality.but its a high profile brand so its make own operating system .IOS Which great compare to android or window operating system.if I want to buy a phone then I see some important specification on the phone.looks, brand, screen size , MRP , GPU and CPU specification.
