According to research by shopping comparison site Kelkoo, almost two-thirds of Blackberry customers are thinking about switching to an iPhone. One thousand Blackberry customers were interviewed – 62 per cent admitted they would prefer the Apple device over other brands.

Research in Motion (RIM) has already been criticised for its slow response to the outage, with customers left wondering what was going on.

Mike Lazaridis, RIM founder, apologised but many believed it was too little too late with customers affected across Europe, the Middle East, Africa and the Americas.

PriceRunner.co.uk, a rival comparison site, backs up Kelkoo’s findings with an almost identical amount of users considering a change in handset.

However, those considering a switch to iPhone may want to be cautious. One editor found her device wiped of all files and contacts. The solution to this would be to back everything up onto a PC prior to attempting an update – and not to rely on iTunes as in this case it failed.

The iCloud is Apple’s new online storage system but apparently, this is not yet firing on all cylinders.

Even so, it is not surprising Blackberry users are looking to the iPhone. So far, an outage on such a scale has not plagued Apple, and as a market leader, it is the obvious choice.
