Gotta have 4

Got my iPhone 4 today , And in my view this here is a massive upgrade from the 3GS( unlike from 3G to 3GS)
The phone hardware is pretty damn sexy.It feels like a piece of art in your hand.Makes my 3GS look old and bulky.The metal finish is absolutely fantastic.

Pics shot on the iPhone4 are way better than the pics shot on my HD2.The camera has auto-focus and zoom(YAY !) and importantly FLASH ! Now iPhones can take pics in the dark too :P !

I dint seem to have any yellow discoloration as many have noted in their devices and NO THE DEVICE DOES NOT LOSE RECEPTION WHEN I HOLD IT IN "THE UNHOLY WAY"
Im not sure how to reproduce this effect.Enough times I tried holding the phone on the lower left corner where the antennas meet and I dint have any issues at all (Weird but good :) )

I had a chance to try out FaceTime with a friend of mine in the US this is pretty much like Skype but you don't have to carry your laptop around :) and no registration or any BS whatsoever

Speakers are a major improvement...I mean they are absolutely fantastic.Way louder than any older iPhone , in fact its as loud as one of those Sony ericsson Walkman phones

Screen is the best improvement Iv noticed so far.When you hold the 3gs and the 4 next to each other you can actually see the Pixel density its way crisper and the icons are more vibrant.But more graphics optimization should be done to the games so that they would look fantastic on the device.

I couldn't find any difference in call clarity .Prolly cause I never did have any call issues in any iPhone I used so far.

Now the olny downside is that you have to cut your sim card to size.
This is relatively easy it took me 5 minuets to cut it .
You need one of those micro Sim adapters if you want to convert it back to normal size.

Multitasking works partially .
I say partially cause most apps currently dont support it.
But all apple apps currently support multitasking , which means when you get a msg while playing flight control or while writing a maail or something you can switch to SMS finish your text and go back to where you left off.
Iv also noticed that when I run 15 simultaneous apps in the 3GS it slows down a bit but in the 4 this isnt an issue at all thanks to the superfast A4 chip !

iBooks for the iPhone is here to stay :D !
so you can carry your whole library of books on the iPhone ( I still prefer the iPad for reading though, cause in the iPhone the amount of text in 1 page is very minimal.)

Safari browsing is cool.But not much changes there.Just that the pages load faster and are more vividly colored.

Last but not least BATTERY LIFE ! Remember how everyone keeps cribbing about how sucky!(can I use that? ) the iPhone battery life is.This one has an amazing battery life Iv used the phone whole through last night and Im still left with 80% battery(and Im considered a heavy phone user).
This is pretty good for start.But I will run more tests and get back to this one.

BTW here is a pic shot with my iPhone 4 in the most disgusting place on earth ! Enjoy
