Every year Apple hits us with a new, shiny iPhone. This year, we are
finally getting features that we've wanted for a while now, such as a
new design, front facing camera, a better quality camera with flash, and
of course a much improved screen.
The iPhone 4 also packs some hidden treats on the inside, making this
the best model so far. Is it worth the upgrade from the iPhone 3G? Did
you just recently buy an iPhone 3GS and you aren't sure if you want to
upgrade already? Or maybe you have never owned an iPhone yet and are
thinking the iPhone 4 might be the time to switch. Keep reading to find
out, and see if the iPhone 4 can live up to your expectations.
Note: Pay attention to all the pictures in this review, as they were taken strictly with the new iPhone 4 camera.
DESIGN & BUILD
Apple
gave the iPhone 4 a design overhaul from the previous 3GS version.
The new model is only 0.37 inches thin, compared to its predecessor
which is 0.48 inches. There is no plastic on the exterior of the iPhone 4, and the standard
silver bezel that was the trim to all previous iPhones is now gone. The
front and back now glass. Supposedly, the glass used is "30 times
harder than plastic", and is "comparable to the strength of sapphire
crystal", according to Apple's Jonathon Ives.
Between the two pieces of glass is an aluminum strip that wraps
around the entire phone. The cool part about this is that the metal trim
serves as an antenna for 3G, Wi-Fi, GPS, and Bluetooth, which helps
signal significantly.
Display
When you first look at the display on the iPhone 4, it is simply
gorgeous. This is without a doubt one of the best improvements on the
new model. The new screen resolution is 960 x 640, up from 480 x 320 on
all previous iPhones and iPod touches. Since the screen didn't get any bigger, there is a lot more pixels
per inch now -- 326 to be exact. Currently, there is no other smartphone
on the market with a screen of this resolution. To the human eye, it is
almost like a digital print. You really can't see any individual pixels
anymore, and everything is more crisp.
It
will only be a matter of time before all the current applications are
updated to support the resolution. The developers have to do little work
to make this change. Now if Apple increased the screen size of the iPhone, that would have
been a completely different story, but I can't see that happening
anytime soon.
Buttons and Controls
On the front of the Apple iPhone 4 you
have the standard "Home" button, along with the proximity and ambient
light sensor, and the biggest change, a VGA front-facing camera. Around the outside of the device you can find the standby button, the
new microSIM slot (which has some improved benefits over the standard
SIM card), a speaker, a microphone, another microphone (that helps
remove background noise), a headphone jack, a silent toggle, and two
separate volume buttons.
