The iPhone 4 has launched
officially today. Right from day one, the iPhone 4 had to endure quite
the storm - people are scrutinizing the Retina Display, saying a yellow
spot has appeared at the bottom, signal reception is reportedly flawed,
the white version is going to be delayed and to top it all off, the
special hardened glass that covers the iPhone 4 went through a nasty
stress test that didn't end so good.

Some people got
their iPhone 4 a couple of days early, but those were the lucky
ones. Most people should be receiving theirs today - and those who
didn't pre-order can walk in a store and buy one (or at least wait in
line and try to get one). If there's enough in stock that is, which reports
say is not the case.

The Retina Display on the iPhone 4 touts an
incredible pixel density plus it should offer amazing image
quality. It's not all rainbows and butterflies though - many users
report seeing easily visible spots with yellowish tint on random spots
on their screens. Some of the yellow
spots that have appeared on iPhone 4's displayFor some it's a yellowish
spot in the bottom of the display, for other the spot can take up a
whole band across the screen. Not everyone is seeing it though - it's
early to tell if this is a common problem or just a few defective units.

Update: Engadget seem to have got the likely cause for the yellow spots. It's supposed to
be some sort of a chemical used for bonding the layers of the screen.
What's more it should evaporate in a few days of use.

Another thing that Apple bragged about was better signal reception on
the iPhone 4. Well, users quickly spotted a problem with that too.
Obviously holding your hand tight over the bottom left corner will cause
the iPhone 4 to go from zero bars to full and back to zero again, while
standing in the same place. Check out this video demo by Engadget.Reportedly, the problem lies
in the lower left corner of the iPhone 4 - holding it with your left
hand so that you hand touches that corner drops the reception bars all
the way down.

In case you were eying a white iPhone 4, it'll be a while before you
can actually get one. Apple says that it has "proven more challenging to
manufacture than expected", so white iPhone 4s won't be available till
the second half of July. Bummer. Gizmodo have a theory or two why that is.

And finally, the guys from iFixYouri decided to
drop it - quite literally drop a brand new iPhone 4... on the pavement.
The glass covering the front and back of the iPhone 4 has been
strengthened to be much tougher than plastic and more scratch resistant.
But obviously that's true (spoiler alert!) only for a head-on impacts
not for side ones.
