Just wanted to quickly point out something to iPhone 3G users since we received a few messages earlier in the week. Its about the release of iPhone 3.0 and now of course in Beta 2, some who have access to the iPhone Dev Center have been tempted to update.
You will already know what great features iPhone 3.0 offers, the latest release of iPhone 3.0 Beta 2 even does abit more. Firstly, APIs for the iPhone’s Push Notification Service have finally been thrown into the firmware, for some reason it wasn’t in the previous version. Secondly, Beta 2 of OS 3.0 now supports up to 11 pages of home screens of apps as opposed to currently nine.
However, iPhone 3G users whether you are currently unlocked with yellowsn0w or not unlocked but want to keep this possibility open in the future, please do not try to upgrade to the latest iPhone 3.0. If you don’t care about having your iPhone 3G unlocked and don’t think it will be necessary in the future neither then you can.
The reason is as many will know the baseband that iPhone Dev Team’s iPhone 3G unlock application works with gets upgraded once you click on the firmware update button. This to date is still not reversible.
The iPhone Dev Team also warns that using the recently released unofficial QuickPwn is dangerous, yes it may offer a jailbreak solution for those who have updated to the latest 3.0 Beta 2 but it may bring with it serious consequences:
That’s because QuickPwn, by its very nature, requires you to already have accepted Apple’s official IPSW, along with its baseband update. If you do that, you will (possibly forever) lose your ability to software-unlock your iPhone 3G.
It doesn’t look like the iPhone Dev Team will be releasing or updating their existing tools anytime soon, mainly because its unecessary for firmwares in beta which already itself contains lots of bugs.
I never thought of this, but it seems some iPhone users update / upgrade their iPhone’s firmware in airplane mode in order to avoid phone calls coming in and disrupting the update process. However it seems the latest iPhone firmware update version 2.2.1 doesn’t like this (it appears that the update requires cell phone signal?). What would or could happen is your iPhone will appear to be stuck or frozen for some time, subsequently a message reporting lost of connection would appear, causing the update to fail completely.
By the way, this applies to those updating directly via iTunes, so no matter whether or not you decide to jailbreak your firmware 2.2.1 after the firmware update, you need to update to 2.2.1 using iTunes anyway first. So it’s wise to be aware of your airplane mode and turn it off to avoid potentially wasting hours of sitting and waiting!
Incase you do run into the situation where you get a completely frozen or bricked iPhone because you left airplane mode on purposely for the update like you usually do, here’s the fix and how to get your iPhone unbricked and working again:
“To turn off Airplane Mode on your seemingly “bricked” iPhone, disconnect the USB cable (or undock), then slide the Emergency Call switch to reach the emergency call phone. You’ll be prompted to disable Airplane Mode. Tap “Disable”. Then press the Home button, reconnect the phone, and watch iTunes recognize/reactivate your iPhone.”
Thanks to Victor from TUAW for pointing this out over at Apple discussions board…
