Since we’re all in the smartphones era, we’re assuming that you have ideas about all the other possible things you can do with your iPhone aside from making calls and sending SMS. We take pictures, listen to music and fool around with our iPhones most of the time but one particular activity stands out the most.

2. Since we’re all in the smartphones era, we’re assuming
that you have ideas about all the other possible things you
can do with your iPhone aside from making calls and
sending SMS. We take pictures, listen to music and fool
around with our iPhones most of the time but one
particular activity stands out the most.

3. A survey of 500 smartphone users in 2010
showed that about 47 percent of mobile phone
users use their smartphones to browse social
networking sites while 62 percent uses their
smartphones for instant messaging. And that’s
just in 2010. Imagine all the other number
changes that have been made in a span of less
than two years!

4. So we know you’re a social network
addict too, that’s okay. You don’t
have to start selling your iPhone just
because it’s getting addictive! Actually,
we’re fueling your addiction with the
list of the top ten apps that are the
most downloaded in the U.S. in the
Apple App Store to keep you in on the
hype machine!

5. It’s that app where you technically bump into each other
and you make lots of friends. It's been downloaded for
more than 75 million times in the Apple App Store and
has been growing ever since. It’s most probably loved by
iPhone users because of the fact that you can easily send
contact information photos and other shareable stuff by
simply bumping phones. You can bump into Android
phones for networking and now it allows your Bump
friends to be your Facebook friends as well. But then
again, it only works for iOS 4 and above so if your iPhone
hasn’t been upgraded, go ahead and start selling your
iPhone!

6. The father of all instant messaging clients on the world
wide web, Yahoo! Messenger still makes it to rank nine
in Apple’s list of most downloaded in its version 2.2.5.
Why does everyone love you? We think one reason is
the fact that we grew up chatting on yahoo (on our
PCs especially since it’s been around since 1998, when it
was still called Yahoo! Pager). Also, it’s always on, it’s
free (the app and the IM service), and it also works
with Windows Live. However, it only works on iOS 4
and beyond so you better start selling your iPhone
original and move on to iPhone 4S (or the upcoming
iPhone 5)

7. If you’re wondering what the heck this app is and you
try to look for it in the Apple App Store we’re advising
you to get your Google Translate ready. Developed by
Sbinteractive.co.kr, Sudapon made it to rank 10 of the
most downloaded apps for iPhone probably because it
looks cute and it’s, well, Korean. Aside from K-Pop
notoriety, it is also loved because of the very appealing
free phone calls and phone chat between its members
and it also works for Android. It’s also free and it has
voice mail. What’s not to love? (Ugh, aside from the
impossible to understand Apple App Store page?)
