Hi all,

Just got my iPhone 3G 16Gb, but now realise it is from AT&T. Believe it should be from US version, and need a Flex Sim adapter.

Notice a lot of limitation, no video mode, no Cydia or Installer icon, don't even think the 3G is enabled as there are no other settings.

I am a newbie, hence have some enquiries as below;

1. Notice the software version is 2.0.1. Don't think this is unlocked yet, correct me if I am wrong.
2. If it is not unlocked yet, is there any software to unlock it?
3. Am I able to install the Cydia or Installer to enjoy the free download?

Appreciate for some advise.

1. you can upgrade to 2.1 (as the sim adapter merely "tricks" iphone into believing that it is an AT & T sim card). however i have not used this adapter before and what i have here is only a hearsay.

2. no

3. yes. JB it

aiseyh... US iphone again?
unlocking by software is out of question bro... still dont have any software to unlock it...
sim adapter? well u can use tht but bare the result...
not sure about JB thou.. if u can Jailbreak it then u can install cydia and installer..

peace

Dear nokia2003 , My set is singtel unlocked unit upgraded to ver2.1 firmware.. can i still use Cydia to download free 'stuff'? Will iPhone lockup or nething? Kinda bored with this phone while dont want waste too much $ on original software.. Dictionary alone already cost me 10usd >_<~

Hi Nokia2003,

Thanks for the fast feedback. JB means to unlock the phone right (unofficially)?

Hence I hear many topics that there is no still no solution to JB the iPhone3G (US), is this still true?

If not, how OR which software is best to JB it? After JB, do I still need to use the Adapter?


Many thanks in advance.

no problem at all. regardless whether yours is a singtel unit (or hong kong, australia, new zealand et cetera), you can still use cydia.


to use cydia, simply JB it. however installer isn't recommend nowadays (as it has passed its good old days).


however, bear in mind that using unauthorised third party apps (from cydia and installer) can potentially cause harm to your iphone OS (and it is not as simple as uninstalling the app) and as time goes by, you might realise that it is getting too slow for your consumption and finally you will need to resort to restoration again.

Hacking and jailbreaking

The iPhone OS has been subject to a variety of different hacks for a variety of reasons, centered around adding functionality not supported by Apple.

With the advent of iPhone OS 2.0, the focus of the jailbreaking community has shifted somewhat. Prior to iPhone 2.0's release, jailbreaking was the only way to allow third-party applications on the device. Now with iPhone 2.0, native applications are allowed under certain rules imposed by Apple. This has lead to the jailbreaking community focusing on providing functionality disallowed on the device, under Apple's SDK terms.[citation needed] These functions include background applications, or the ability for third-party applications to run after appearing to have closed, and the ability to alter the applications written for the device by Apple, also they thought could disable the Apple kill switch (that allows Apple to remotely delete malicious or inappropriate applications stored on the device). [40] The kill switch was later proven to be less invasive, and the only control Apple had over applications was killing the use of core location (location based services). There has been a notable shift away from jailbreaking with the new App Store's debut, in most part due to users' acceptance of Apple's compromise on opening up the platform,[citation needed] although there has still been substantial interest from the jailbreaking community, especially with the release of Pwnage Tool from the "iPhone Dev Team" which was released soon after firmware 2.0 for the iPod Touch and iPhone.

Nokia, Thanks for your fast reply! I think, better stick to original software

Hi TS,
Don't be disappointed if i say NO WAY for you to unlock your US iphone3G..
For JB to firmware 2.1, yes.. JB is not unlock, JB just allow you to install any 3rd party application directly without going through itune..
That is why, do survey & collect more infor first b4 buying..

no matter unlock or locked iPhone still can JB. Dun take unlock and JB pull in together.
Currently no software unlock, but u can JB . If u cant wait..u can use hardware unlock, turbo sim to unlock first.
After JB..u can get application through cydia(iPHone wifi) or using cable connect to pc( iPhone tunnel suit) to get application downloaded from internet to PC.

y alot of ppl like to say jailbreak=Unlock or Unlock=to jailbreak......

jailbreak = in order for you to install 3rd party software, at the same time u still can install d software download from appstore..


unlock = in order for u break free.......n use whatever telco u like........

My iPhone is currently V 2.0.1 (US). Can this version be jailbreak? Or do I need to upgrade to 2.1 before JB?

you can jailbreak it even you in v. 2.0.1 or 2.1, i strongly advice you upgrade 2.1 then jailbreak it so that you can install 3rd party application.
but to use it you have to buy/use "hardware unlock sim" so that you can use it, but bear in mind that if you use sim unlocker your "phone line will not stable ( sometime will get call failed and etc but not much i guess ).....


just wait patiently because there will be a software unlock but how long we will wait is out of a question because all of use cant answer that question on how software unlock will be release..



here is example of "sim unlocker" i mention about.... http://forum.lowyat.net/index.php?showtopi...25&hl=turbo+sim

Any instructions OR procedures to upgrade to 2.1 and then JB it? Thanks in advance. Forgive me, I am new to this thing.

Yes..just follow this thread..
http://forum.lowyat.net/topic/796445

The Dev team havent have the unlocking software yet
But actually my friend in the US unlocked his AT&T using siftware already..
I've seen when i skype with him..
He say he's not gonna put it online so too bad... =p

Note : I won't be responsible if my friend if lying but i don't think so..

When I first bought the iPhone 3G (AT&T set), the shop in Singapore gave me a turbosim solution that needs to cut a hole on my simcard. I was conned because it works intermittently. When i reached in Malaysia, it does not work at all.
Thus, I'm left with an "expensive iPod Touch with camera" for about a month.
Recently, I have the courage to use another turbosim solution which does not modify/cut my simcard.
It works wonderfully (almost perfect) except at times I cannot receive any calls. Need to reboot if this problem occurs.

I have upgraded and jailbroken the iPhone 3G using pwnage tool. Now its FW 2.1.

However, I'm still waiting for the good news from Dev team (it seems they managed to progress to some level now) for a software unlock.

Common problem using turbosim.
At times no service - just reset network. From Setting-General- Reset.
Or do not off the phone. Once the phone shut off it will take some time to search network then no sim will appear.
Certain version turbosim will support Celcom but not necessary will work on other telco.
I have changed my turbosim, 3X.

wow... 3 time huh?

1st - no service can last for 4/5 hours
2nd- no 3g signal
3rd- so far ok

moral of the story

Do research first before buying any gadgets and say NO to TurboSIM (Or anything close to it).

Hi de_lasoul,
Can share your experience using your LOCK AT & T iphone3G by using Turbo Sim/hardware SIM.. U faced any problem?
