Are iPhone owners is worse financial shape than the population in general? Those are the findings (in the UK anyway) of a new YouGov poll, first reported by The Daily Mail.

We already know iPhone buyers are a finicky bunch, like Apple customers in general. For many, buying an iPhone is just the beginning. From there, you need to buy the perfect case, and of course, load it up with hundreds of apps.

However, a new survey suggests that iPhone buyers are doing so while being in debt.

According to the YouGov poll, one in five iPhone owners always has an overdrawn bank account. In addition, iPhone owners are said to be poorer than their Android or BlackBerry counterparts.

The YouGov poll found 20 percent of iPhone users have an overdrawn account, which is double the national UK average. In comparison, the same survey concludes 54 percent of those who own a phone that uses the Android OS and half of BlackBerry owners say they have never overdrawn a bank account.

In addition, the survey says that 10 percent of BlackBerry owners earn more than £50,000 a year ($80,000), compared to just 5 percent of iPhone owners. Seven percent of Android customers have a salary in this range.

Finally, half of iPhone owners earn less than £20,000 a year ($32,000), compared to 38 percent of Blackberry owners and just 27 percent of Android owners.

The poll surveyed 2,000 smart phone buyers.
