While the previous iPhone 3GS didn’t bring much of a design change to
the iPhone 3G, Apple’s iPhone 4 has undergone a decidedly new look
that’s very different from the previous generation. Most readers would
already be aware of the changes, seeing as how the phone has been
available in the US for just over a month, so it’s about time the phone
was launched in Singapore.
We got ourselves a review unit at last and our initial impressions of
the unit seemed to bode well for us. The iPhone 4 felt and looked sleek
and gorgeous compared to the iPhone 3GS. Furthermore it comes with new
features and upgrades, that we’ll be touching on in the next few pages.
While the reports of an antenna issue with the iPhone 4 have been making
the rounds, we’re hoping that our better network coverage will offset
this problem. We’ll do a little more testing in the next page; for now
though, let’s take a closer look at the exterior.
iPhone 4 is thinner compared to the iPhone 3GS, but it is two grams
heavier compared to its predecessor. Both the front and the rear are now
clad in aluminosillicate glass, the same type of glass that’s found in
helicopter windshields. Apple says it’s pretty scratch resistant, and
with glass on both sides, we’re hoping this is the case too.
The iPhone 3GS also looks like it's slightly wider at the edges, compared to the iPhone 4.
Apple iPhone 4 does retain some design similarities as previous models.
For instance, the only change at the top is the removal of the SIM card
slot and the addition of a second microphone for the noise cancelling
If you're looking for the SIM card slot, it's now at the right hand side and has been changed to a Micro-SIM slot.
On the left, the usual mute switch and volume controls.
And at the bottom, we have the usual 30-pin connector, microphone and speakers.
