iPhone 3Gs Unlock - 3.0 Firmware

How many of you have been using the Apple iPhone, but have never tried to unlock it? Is it because you are happy with what you have or are you apprehensive of experiencing ‘a revolution’? Well, I’d say, it’s true as we sometimes resort to the famous saying ‘Ignorance is bliss’; but what about missing the fun and adventure when the whole of iPhone world goes crazy about iPhone unlocking and iPhone Jailbreak.

I have tried to make a careful study about the apprehensions regarding the unlocking or jailbreaking of iPhone; and the results I found are quite startling. It is not always that people are happy with what they have, but they still do not want to try unlocking. Most of the iPhone user’s apprehension to opt for iPhone unlocking or Jailbreaking is due to their lack of proper knowledge or clarity of concepts relating to the same. Many of them I spoke to weren’t too sure about the differences between Unlock iPhone and Jailbreak.

Here it is, kiddies: the latest iPhone. Just one year after Apple announced the iPhone 3G, the iPhone 3G S has been announced. There is much to love in this update including larger storage options, a faster CPU, HSDPA support and a better camera all for the same price as the current set.
The OS should now run faster thanks to a 50% bump in CPU speed; it now runs at 600MHz. The system memory has doubled to 256MB as well.
Apple didn’t forget about the camera - well, sortof. The iPhone 3G S did get an upgrade in that department too, but it’s only with a 3MP camera. It does finally support auto-focus, but it’s still not up to par with other flagship smartphones. Plus, this iPhone can now shoot video at 30 FPS with auto lighting and auto focus.
The new hardware will come in both 16GB and 32GB options with black and white models available in both sizes. These options will be available in July for $199/$299 respectively. Battery life has improved as well and Apple is claiming that the iPhone 3G S will go 15- to 20% longer on a charge. But no, the battery still isn’t usre replaceable.
The new hardware is welcomed, but the 3.0 software has also been updated with a new feature set. You can now tether - yes, tether - the iPhone via USB or Bluetooth to either a PC or Mac on 22 carriers worldwide; sorry, AT&T isn’t one of them. Speaking of AT&T, MMS will be available sometime this summer through an update. Or so they say.
But at least users can now rent and buy movies right from the iPhone. That’s a win, right.
Anyway, a new feature that most will love is the Find My iPhone. It’s a service for MobileMe subs that, well, finds your lost iPhone and displays its location on a map. It could be a great way to keep track of your spouse too. When activated, you can message your iPhone with a number to call and it will sound a tone even if the phone is on silent. Or you can remotely erase all of the data on the phone.
All these software updates also apply to older iPhones as long as they are loaded with the 3.0 software pack available worldwide on June 17, 2009.
Apple has kept the price point of the current options. So the 16GB will run $199 with the 32GB fetching $299; both are on-contract prices of course. Phil Schiller didn’t mention if current iPhone owners in an AT&T contract will be able to upgrade without penalty, so expect the official word from the carrier soon. AT&T did just that last year when the iPhone 3G was announced.
Expect the lines to start forming now ’cause the new iPhone 3G S will be available on June 19, 2009 in the States with the rest of the world getting on July 9, 2009. The iPhone 3G gets its $99 price starting today though.
Update: Remember how last year AT&T let current iPhone owners upgrade without penalty. Yeah, not going to happen this time around.
From the iPhone product page down in the fine print:
Requires new two-year AT&T wireless service contract, sold separately to qualified customers; credit check required; must be 18 or older. For non-qualified customers, including existing AT&T customers who want to upgrade from another phone or replace an iPhone 3G, the price with a new two-year agreement is $499 (8GB), $599 (16GB), or $699 (32GB).

iPhone firmware 2.2.1 Breaks Software Method to Unlock iPhone 3G

Ziphone 3G Blog

Apple released iPhone firmware 2.2.1 yesterday which included minor bug fixes and improvements as per the release notes.
However, it looks like there was another reason for releasing the latest firmware. The Dev Team who had warned against updating to the latest firmware has confirmed that iPhone firmware 2.2.1 breaks the “injection hole” that they had used in their application yellowsn0w to modify the firmware which had helped to successfully unlock iPhone 3G.MuscleNerd, a member of the iPhone Dev Team who had released World’s Software method to unlock iPhone 3G on 1st Jan 2009 had this to say over Twitter:for *jailbreak* purposes 2.2.1 is fine for all including ipt2g. But it BREAKS the yellowsn0w soft *unlock* for iPhone 3Git’s not surprising that they fixed injection hole for yellowsn0w, it is surprising to see a “silent” update
the iPhone 2G baseband is untouched .. I *think* they’ve stopped all development of it last update for it was 8 months ago
He has also broadcasted a video on Qik to explain what it means if you upgrade to iPhone firmware 2.2.1.As we had reported yesterday, iPhone firmware 2.2.1 also updates the baseband (modem firmware) from 02.28.00 to 02.30.03 thus breaking the software method to unlock iPhone 3G.
Options if you have already Upgraded to iPhone Firmware 2.2.1:
So if you have upgraded your jailbroken and unlocked iPhone to firmware 2.2.1 (or just about a new iPhone which came pre-installed with firmware 2.2.1), then you are left with the following options depending on your version of the iPhone:
1st gen iPhone: Since the update does not touch the baseband of the 1st gen iPhone your unlock will remain in place. However to jailbreak your 1st gen iPhone you will need to wait for the dev team to release updated versions of PwnageTool and QuickPwn tools which will let you jailbreak your 1st gen iPhone running firmware 2.2.1.
iPhone 3G: The Dev team should soon release updated versions of their PwnageTool and QuickPwn tools to jailbreak your iPhone 3G running firmware 2.2.1. But since the latest firmware updates iPhone 3G’s baseband to 02.30.03, you will not be able to unlock it. You will need to wait for some time for the Dev team can unlock baseband 02.30.03.
Options if you have NOT Upgraded to iPhone Firmware 2.2.1:
In case you have jailbroken and/or unlocked your iPhone but haven’t upgraded to the latest firmware then then your options based on the version of your iPhone are mentioned below:
1st Gen iPhone:
If you do not care about jailbreaking but only worried about unlocking your 1st gen iPhone then you can go ahead and update your 1st gen iPhone as the update does not touch the baseband of the 1st gen iPhone so your unlock will remain in place.
If you care about jailbreaking then you need to wait for the dev team to release updated versions of tools which will let you jailbreak your 1st gen iPhone running firmware 2.2.1.
iPhone 3G:
Please avoid updating your iPhone with the latest firmware until the iPhone Dev Team have not released the latest version of PwnageTool. The latest version of PwnageTool for iPhone firmware 2.2.1 will help you to safely upgrade only the iPhone firmware to 2.2.1 and not the modem firmware.
Lets hope most of you had read our post yesterday or read this one before updating your iPhone with the latest firmware.
The cat and mouse game between Apple and the dev team continues. Let us know your thoughts in the comments below.
Update:
These comments by MuscleNerd over at Dev Team’s blog should clarify things further, we have also updated the post accordingly:
In fact, until a lower-level (”hard”) unlock comes out, yellowsn0w users should *always* avoid official updates — they should only update through custom firmware IPSWs made through our various pwnage tools. These custom IPSWs can update your main firmware without updating your baseband (which would kill the yellowsn0w injection exploit).
Since this update doesn’t touch the iPhone 2G baseband, your unlock patch will remain in place. So for iPhone 2G owners who care only about keeping their unlock — not about jailbreaking — you can take this update right now.
