Less likely. The iPhones that are available at Maxis are probably old stock and hence run on iOS 3.

But I'm sure you can get them to upgrade for you.

Thanks... already e-mail them to ask.... (lazy to drive & beat the traffic jam to go to Maxis centre to ask....)

just wanted to know now...maxis centre already closed... will find out tommorow.... just ask here ...in case
any Bro have the answer now...

haha if u hv an existing maxis line. call 123? thy "might" know..

but yea.. i doubt ios4 is preinstalled in the 3gs.. thy jus released it not too long ago.

but honestly.. i still prefer the 3.1.3.. so much more stable. pros and cons..

i notice my battery life isnt as long as well.. sweat.gif

Okay, I don't get it. What does that have to do with the antenna? Sure, it uses a different chip. But if the antenna is the problem, it doesn't really matter what chip it uses, does it?

Note: No intention of stirring up an argument. Just looking for answers. smile.gif
*
I saw your comments so I thought of giving you further insights into the problem. Actually the chip does play a major role in signal quality and reliability during calls/connection. With IC advancement and RF design, efficiency would be better. The iPhone 4's RF chip probably receive 1 full year of innovation since 3GS so it could be more sensitive to signals kinda like how a new GPS chip is better and more accurate than previous one.

Also new IC would allow new features or better control by firmware programming. As a result, handling of 2.5G/3.5G radios would be better especially the transition from one radio to the other when you move around. Also the handling of transfer from one cell to the other. It is typical for the phone to switch from 3G to 2G when 3G signal is weak and only to switch back to 3G when signal improves (due to power consumption and signal quality). With the typical antenna placement on the bottom of the phone (due to SAR requirements), this problem is amplified. Most dropped calls happen here when the phone switches radio. However, the base station also play a role in the handling of switching. And we all know AT&T's infrastructure is dodgy hehehe, so this is nothing new. This is also a limitation in the current mobile infrastructure we're using now.

Another factor in dropped calls is when you move from one cell to another cell. The phone needs to register to the new station and service is transferred. MOst of the time this is transparent to us. Sometimes handling isn't smooth and you will get dropped calls. Anyway going back to the RF IC, there was suspicion that the IC used on 3G/3GS was flawed. So it does play a role in this issue. The antenna design serves to improve the efficiency of the whole setup and is just one part of the problem. By the way, there are reasons why antenna 'should be inside' the case. Hehehehe... There's one way to improve signal quality via antenna design. That is to adopt a 3D plane antenna. A good example is Acer's 3D WIFI plane antenna used on most of its laptop. The isotropy of radiation and its pattern is more evenly distributed. But you need more space, something iPhone doesn't have.

Before I forget, switching policies does make a difference too. For example, 3G preferred or 2G preferred or 3G only/2G only, etc. The policies are usually set in the interest of power consumption (due to near far phenomena of GSM radios) and signal quality vs signal strength. Sometimes strength doesn't mean anything when the quality is low.

These are some of my insights and 2 cents.

If your SIM is the older version, then yes, you will have to cut through the golden area of the chip. Latest simcards will have the gold chip size smaller and after trimming it down, it will still be possible not to damage any of the gold chip part.
*
Yes, you can cut into the 'golden area' or otherwise known as the module tape/contact patch as long as you don't cut into the module hidden underneath it. The contact patch is just a larger area and can be trimmed. The SIM friction pins in the phone is electrically compatible and only needs a small area of contact to work. There is a lot of tolerance to play around.

My aunt claimed VAT for her iPad from London.

I too am hoping it will go through for iPhone4 as my cousin will be helping me get a unit from London as well.

After I upgraded my i3GS from 3.1.3 to iOS4 yesterday morning around 7am, everything working fine till yesterday midnight. I tried to sync my i3GS with iTunes. Syncing successful except for back up. I can't back up my i3GS. Error said iTunes could not back up iPhone because iPhone disconnected, pop up and I little panicked. Then i tried to restore back my i3GS but the the restore finished it halfway and error 29 pop up. My i3GS stuck at recovery mode. Then i do some research and finally I kicked out from recovery mode and also managed to restore back my i3GS but something bad happened. My i3GS keeps restarting after a few minutes especially when it is on charging or when I using it.

Is it iOS4 bug or my i3GS's hardware faulty? Before this my i3GS had been water damaged and recover from it. Only headphone jack defect. Is it possible to change the water damage indicator to normal and go claim warranty or iPhone repair shop could repair it if i3GS warranty has ended up?

after i repaired my faulty headphone jack. i tried to restore to iOS 4 and no more error 29. i'm so happy right now. rclxm9.gif

i dont know if this is a good news or not for u guys... but for me it is a GREAT news....

people who already have iphone 4 at www.head-fi.org mostly agree that the sound from iphone 4 is much better than iphone 3gs.....

On another note, Apple is releasing iOS 4.1 as fix for the antenna problems some time next Monday. thumbup.gif

i wonder... izzit can be done by just software....

and would it consume more power since it'll need more power just to suck the line? just my theory.....
but good findings.... we'll wait for this monday...

Left hander gonna face the problem of dropping signal, according to my friend's experience.
Perhaps he should get a Bumper.
Me myself don't have much problem for the signal dropping issue, I'll just try to avoid holding it that way.

Technically its not easy to fix the antenna problems with a software unless the iPhones are using some sort of smart antenna technology which uses software to "tunes" the signal strength (which I don't think Apple is using) coz they have boasted about the new Antenna body design.

Hardware method is the easiest way and that's why they introduced the iPhone 4 case "bumper". Technically its called "RF absorber". Many designs have used this method to reduce the RF interference. However, I am not sure other "plastic case" design by other manufacturers have same quality as Apple Bumpers or not.

However, I believed the software patch (as mentioned by Apple Insider) 4.0.1 (if released) is not trying to solve the Antenna problem but instead the software patch is trying to close any security holes for Jailbreak solutions. brows.gif

With 3gs iOS4, noticed that the IP add for my home wifi is not correct. It displays a wrong IP add.. tried to manually key in still no avail.. tried reset the network, also fail.. normally when we take out the simcard, we still can surf thru wifi, right.. but this 3GS with iOS4 cannot..

Hppefully with the release of iOS4.1, this issue will be solved.
