Reliable OS 'increasingly important'
A strong and reliable operating system (OS) will become an increasingly important option to consider for consumers looking to upgrade their used phones, if recent suggestions are anything to go by.
Independent technology and market research company Forrester Research recently suggested that the introduction of electronics company Samsung's bada mobile OS and mobile operator Nokia's Maemo OS will lead to further fragmentation of the market.
Leigh Geary, from CoolSmartPhone.com, said: "I doubt the iPhone will have any trouble for at least another year or two. It's very successful, but Apple need to worry about their biggest problem – themselves."
He added that a possible upgrade to the iPhone in future is a higher resolution screen but that this will instantly break all their apps and will cause fragmentation, therefore, the OS which keeps it under control will succeed.
Mobile fragmentation is the inability to develop applications that are "write once and run anywhere", according to the National University of Singapore School of Computing.
