Apple has 84 per cent customer loyalty

But 52 per cent of RIM customers have itchy feet.

Research firm GfK says Apple is leading the charge with customer loyalty ahead of rival phone makers as 84 per cent of iPhone users said they would choose iPhone again when they replace their current device.

Android is second with 60 per cent of consumers saying they would return to Google's OS, while just 48 per cent of RIM's BlackBerry customers would stay true and return.

That's no surprise given the inconsistent service RIM has given customers over the past couple of months. At the time of the October power outage, many customers took to social networks to voice their anger at the lack of communication from the firm.

The report says that on 63 per cent on average will stick with the phone they have, which means brands will have to work hard or fail miserably in order to command change in the market.

Ryan Garner, analyst at GfK, said: "Apple is clearly ahead of the game, but developments next year will challenge that."
