Last week our site iPhoneRoot.com was contacted by Wall Street Journal journalist to comment on recent iPhone antenna and signal issues. We certainly shared our thoughts. After interesting conversation we agreed to perform a research of the latest iPhone iOS 4firmware. As a result WSJ published two interesting articles covering iPhone, antennas, signals and bars. Take a look:
iPhone 2G and iPod touch 1G do not officially support iOS 4. However there is a project called WhiteD00r that aims to bring iOS 4 functionality to iPhone 2G users with a custom firmware bundle.
This bundle is created by Matteo Morando and is based on firmware 3.1.3. It is built with PwnageTool. It incorporates several utilities to adds iOS 4 features such as multitasking, wallpaper, tethering, sms count, and more.
There are 3 different versions - Lite and Full for iPhone 2G and one for iPod touch 1G. Here is the complete feature list:
MuscleNerd from the iPhone Dev-Team announced via twitter that an unlock for iPhone 3GS with 05.12.01 baseband from iPhone firmware 3.1.3 will be released soon:
@MuscleNerd will there be a unlock software coming out for the 3gs 3.1.3 baseband 05.12.01 when the new iPhone 4g comes out??
@EmmanueGT yep..so don't sell or give away your 3GS (at same time, remember not to accept Apple FW upgrades in future)
Last week Apple has released its iPhone Os 4.0 beta 4 and redsn0w is finally updated to support this as well as beta 1. New version of jailbreak is 0.9.5.b4 and it can be applied on iPhone 3G only(!).
Redsn0w 0.9.5.b4 is targeted at developers who make jailbroken apps, and will not work if you are already using blacksn0w, ultrasn0w or yellowsn0w.
iPhone Dev-Team warns:
"You should stay clear of this beta software if you rely on a carrier unlock."
To use the jailbreak, follow the guide below:
Download redsn0w 0.9.5.b4 here. (Only Mac OS X version since app are developed on this OS).
Make sure you have already activated your iPhone 3G with iTunes and your own developer ID.
Launch the jailbreak.
Select your stock iPhone1,2_4.0_8A274b_Restore.ipsw (beta4) or iPhone1,2_4.0_8A230m_Restore.ipsw (beta1) file that you used to update your firmware.
Choose "Install Cydia" and then click "Next". Use DFU mode to install the redsn0w.
When your iPhone 3G comes back up, you will notice Cydia has a blank white icon. It also has no sources so you should go to the Sources panel and add this repo: http://apt.saurik.com/cydia-3.7 (make sure you are connected to the Internet before). When Cydia restarts, you should see its real logo now, and the standard sources should be ready to use.
Those developers who study new beta-versions of iPhone OS 4.0 reveal that new firmware has features of suggested word replacement and spellcheck imported from the iPad to the iPod touch and iPhone. They were presented first in iPad which has iPhone OS 3.2.
Spelling system allows users to select a misspelled word with a touch and then choose «Replace...» instead of using copy/paste operations. The word that was misspelled is underlined in red like in Mac OS X or Microsoft Word. After that system offers replacement word suggestions that also can be chosen with only one touch.
Apple announced that iPhone OS 4 will also allow iPod touch and iPhone to support iPad's Bluetooth keyboard.
An unknown group of hackers work now on bringing current beta version of iPhone OS 4 to the iPhone 2G (that was released in 2007). As you remember, Steve Jobs mentioned on his iPhone OS 4 keynote that the system won't be supported by iPhone 2G due to its low memory and processing power. Hackers also explained what they are working on:
"We are rewriting the 4.0 beta firmware released by Apple to create a custom firmware that can run on devices iPhone 2G which is no longer available. To do this we studied the architecture of the firmware previously released by Apple on the device trying to understand how is it different from the released versions on other devices, in particular that of the iPhone 3G device, which is what most resembles the smartphones".
According to a shady photo above they've already reached success but still there is no relevant information revealed on their site.
Finally the jailbreak for iPad, iPhone and iPod Touch from the Dev Team is available for download. It's free and untethered and it's called "Spirit". The jailbreak supports every iDevice with firmware version 3.1.2, 3.1.3 or 3.2.
