New survey shows that iPhone users are more intelligent than Samsung, BlackBerry and HTC owners

The brand of phone you uses can not only say a thing or two about your income and lifestyle, but can also indicate how intelligent you are too. How true can this be?

A thousand smartphone users were challenged to take a series of online brain teasers designed to test their mental agility.

iPhone users were found to have the quickest wits of all, completing the test in 94 seconds, on average, while BlackBerry users were the slowest at 118 seconds.

The test was carried out by UK bookmaker Ladbrokes who picked the participants from a list of people who use its smartphone app.

The Test of Wits is made up of seven brainteasers designed to test problem solving skills, pattern recognition and code cracking.

Each question has four possible answers and a participant has to select the correct answer before moving onto the next teaser.

Example questions include:

How many 9s are there between 1 and 100: 

a) 19  b) 20 c) 9  d) 1 e) 14

How many months have 28 days: 

a) 1 b) 12 c) 24 d) 10

How many legs do 2 dogs and 2 ducks have in total?

a) 8 b) 10 c) 12 d) 14

Each user is asked to select their make of handset before completing the test, and a timer in the top right-hand corner records their speed.

A study in August found that iPhone owners are vainer and spend more on clothes and grooming than those who have BlackBerrys and Android phones.

BlackBerry owners earn the most and are more likely to have long-term relationships, while people with Android handsets have the best manners and are handy in the kitchen.
