I had dead pixel and stuck pixel on my screen previous. Notice that I use the word 'had'. I went back to get a replacement.

Hmmm..... Share with you all..
My iPhone 4 is SG set,
1.) I don`t have any antenna issue so fat, even I death grip it, the signal will not drop to zero, it will remain 1,2 bars.
If I hold it right, it`s 4, 5 bars. Today I went Quill Automobiles BMW and get a OZAKI ICoat which cost me RM70. The signal problem totally solved.

2.) My screen don`t have any yellowish tint, even I tried view FULL WHITE wallpaper.

3.) I am running 4.0.2, so far I don`t get any bug yet, or maybe I haven`t try it out.

I wonder should I upgrade it to 4.1 through iTunes, because I saw a few of you get bricked or stuck. Any suggestion?

Not with casing. My exp if only u hold it without casi g on your left hand and bridged the gap then the bar will drop. If ur area have gud signal strenth then theres no prob. Or hide the issue by ising bumper or case

Your safest bet during upgrade will be to use window 7/window xp loaded computer. Be sure to get the latest itune before doing so. I have seen several ppl facing problem with window vista (I myself was one of them)

Thanks bro
If I do, I will upgrade it through my laptop which running Window 7 HP and latest iTunes.
Really feel sorry to you. So yours is get stuck? and going to get a replacement?

Beside, is there any new features with 4.1? anyone can show the HDR effect?

Not sure is the problem or not... my i3gs original wallpaper more "white" side compared with my new ip4 original wallpaper which look a bit "yellowish"

It's fine. I manage to restore it using a window 7 loaded laptop. The HDR effect really depends on the lighting condition. For an outdoor shot, especially under a bright sunlight, HDR can help you to dim the over exposure and enhanced the photo details but it tends to lower your color saturation. IP4 will save both pictures so you can choose either one.

I don't think HDR works well for all shots but I think it is pretty handy since it is does an automated correction to your picture (which of course doesn't always appear to be what you want).

The battery life is also not as long as I expect it to be. But i think I know why. It's likely because of the numerous apps that run in the background unless you exit it manually from the task switch bar.

My iphone4 doesn't feel awesome to be used unless it's jailbroken!

Start paying for apps and iP4 is awesome again

which version of itunes suitable to upgrade IOS4.1?i'm using itunes 9.2 version?is it want to install 10 version?how do i updrade to IOS4.1?

Upgrade your iTunes to iTunes 10.
Plug in your iPhone and click restore. Sit back and enjoy the loading process.

do we really need to use screen protector for ip4? plz advice

My personal opinion is definitely a 'YES'. It isn't scratch resistant. The problem comes when you put it in your pocket together with other things especially keys!

i tot it's glass was scratch resistant?
maybe im wrong...

scratch resistant DO NOT 100% resist it okay?!
it would only reduce the scratch chances.....
We still need a SP for iPhone 4!

Well, it might not scratch as easily as normal glass but it isn't scratch resistant. Google around and you will find how people complain about scratching their IP4.

That is why I have back and front protectors all the time just to be extremely sure. Afterall, it is worth to be extra careful with your new found joy!

i recommend the crystal clear SP by powersupport honestly.
when i first got the iphone 4 i straight opt for the cygnett opticclear anti-glare SP.
it's good for playing games and all and has the matte feeling but i don't get to really feel the retina display cause it kinda deteriorate it when lowered the brightness compare from the crystal clear .
switch to crystal clear and the crisp of the display is just much better.

the crystal clear is definately for me i recommend.
but at the end of the day it is still the user preferences

Yes, I don't really prefer anti-glare SP since it will 'obscure' your screen making your retinal display looking rather 3gs like (sorry not saying 3gs is inferior).

If you buy switcheasy case, they will give you free high quality SP. Most cases you buy from ebay will give you free SP too. So guys, trust me, it's worth the extra bucks just to keep your IP4 at its pristine state.

yes agreed that the crystal clear sp will give you better eye seeing and for the retina display..
however the crsytal clear sp always left fingerprint/oily surface (if you got oily face) right on your back & front sp?
currently im using the clear sp from powersupport...need to wipe both sides oftenly if want to keep your phone look nice & tidy

i was about to ask the quality if apply anti-glare SP. thanks for all the review. any recommanded crystal clear sp for intro? coz i got myself a cheapo SP form some random h/p shop. it wun stick on my screen left some bubble on the top n bottom right corner of the screen.
