Our recent discussion of mobile banking sites for the iPhone highlighted the fact that many people can't access their banking applications on their mobile device, whatever flavour. However, the situation may be set to improve. A recent survey by Sybase 365 suggests that a third of global banks already offer some mobile banking features, and a similar number expect to do so over the next year. That's partly driven by consumer demand: almost a quarter of customers surveyed said they would switch banks to get access to a mobile net banking service. Are you able to access your bank on your mobile phone, and is that a useful feature? Share your thoughts in the comments.
