As it is expected that Apple will unveil the iPhone 5 next month, it appears that there will be quite a strong demand for the new iPhone once it becomes available, something that shouldn’t really shock anyone in the mobile space, and a recent survey seems to concur that there will be strong demand for Apple latest iOS handset.

According to a report over on Barrons, William Power, an analyst for Robert W. Baird has conducted his own survey on the subject, taking in some 2000 participants and has found that 36 percent of those surveyed are eligible for an upgrade whilst another 6 percent can upgrade in the next three months, and of those, 45 percent plan on buying an iPhone, with the majority waiting for the iPhone 5.

Apparently 31 percent of those surveyed stated they are undecided on which smartphone to purchase next, whilst 22 percent are planning on buying an Android smartphone.

According to Power, if those percentages hold up, it could suggest that there could be 50 million+ iPhone 5 sales in the United States alone, which he says is well above current forecasts.

Unsurprisingly iPhone users are the most loyal as well, with 77 percent of iPhone users planning on moving up to the new iPhone, although 5 percent were planning on switching to an Android device, and 18 percent were undecided. When it comes to Android loyalty, 48 percent will remain true to Android whilst 17 percent are expected to switch to the iPhone, and 34 percent are undecided.

When it comes to BlackBerry, it appears that RIM has basically lost any real loyalty they once had with just 2 percent stating they will purchase a new BlackBerry handset.

Lastly when asked about an Amazon phone or Facebook phone, it appears the Amazon phone would fair better than a Facebook phone with 51 percent of consumers saying they would consider purchasing the Amazon phone, whilst just 7 percent said they would be interested in a Facebook phone.
