Καλή Χρονιά σε όλους!

To 2009 μπήκε με το δεξί για τους κατόχους του iPhone 3G καθώς η devTeam κυκλοφόρησε το Yellowsn0w (διαθέσιμο από το Cydia/Installer) και πραγματοποίησε την υπόσχεση της για Unlock του iPhone 3G!

Για να ξεκλειδώσετε το iPhone 3G θα χρειαστεί αρχικά να το κάνετε Update μέσω του iTunes στην v2.2 (ώστε να αναβαθμιστεί η baseband στην 02.28.00).
Όσοι είστε ήδη στην v2.2 αλλά έχετε διαφορετικό baseband* θα χρειαστεί να κάνετε Restore μέσω του iTunes στην v2.2.

*(Για να ελέγξετε σε ποιό baseband είναι το iPhone σας πηγαίνετε στο Settings->General->About->Modem Firmware. Το Modem Firmware είναι το ίδιο με την baseband)

Στη συνέχεια θα πρέπει να το κάνετε Jailbreak με το QuickPwn ώστε να εγκαταστήσετε το Cydia/Installer:

iPhone 3G Jailbreak (MacOs): QuickPwn
iPhone 3G Jailbreak (Windows): QuickPwn

Προσθέστε τα ακόλουθα sources:

* Cydia source: http://apt9.yellowsn0w.com/
* Installer repo: http://i.yellowsn0w.com/

- Εγκαταστήστε το Yellowsn0w.
- Πηγαίνετε πίσω στο main menu του Cydia.
- Κάντε Reboot το iPhone έχοντας μέσα την SIM σας.
- Περιμένετε να εμφανιστεί το “Slide to unlock”…
- Περιμένετε ακόμη 10-15 sec.
- Αν δεν δείτε το σήμα του παρόχου σας (carrier logo) βγάλτε την SIM και ξαναβάλτε την… Περιμένετε 10-15 sec.
Αυτό ήταν!

Μερικές χρήσιμες πληροφορίες από την DevTeam:

BASICS

* The unlock about to be released works exclusively with baseband 02.28.00. This baseband is provided by the latest firmware update (2.2) from Apple. You’ll need to upgrade to this release using iTunes and then use QuickPwn to activate etc. Because it works on 02.28.00, it is available to everyone on the planet. This means we don’t need to unnecessarily expose holes in earlier basebands, which is an important concern.
* The application is a small daemon that is launched on boot. It injects the payload at boot and also whenever there is a baseband reset. You won’t notice anything about it other than that your third-party sim now works. It’s a small program and unobtrusive. There is no GUI (this is by design).
* yellowsn0w is completely removable through Cydia, the command line, and iTunes.

KNOWN ISSUES

* There is a known issue with SIM cards that have STK (SIM Toolkit) application menus. These menus are usually items such as “top up” “get credit” etc. These menu items confuse the application sometimes. Removing and reinserting the SIM once after reboot (give it about 10 secs after you see the slide to unlock widget) fixes this issue. We’re working on a better fix.
* For those of you using SIM cards without STK menus, the application has some optional arguments that will make the unlock much faster for you. So either experiment on your own (use “yellowsn0w -h” for usage) or wait for a customization writeup.
* After you install yellowsn0w via Cydia, you should return to the Cydia main menu then reboot your iPhone with the 3rd party SIM installed. Wait for the slide to unlock screen, then wait 10 or 15 secs more. If you don’t see your carrier name pop up, then remove your SIM, reinsert it, and wait 10 secs more. This is the step we’ll be working on eliminating next.

Σημείωση: Η είδηση δεν αναφέρεται/ενδιαφέρει όσους προμηθεύτηκαν το iPhone 3G από την Vodafone GR (καθώς είναι ήδη unlocked) παρόλα αυτά αποτελεί ευχάριστο νέο για όσους έχουν προμηθευτεί το iPhone 3G από άλλες χώρες όπου και πωλείται SIM locked.

UPDATES

1. Soon you’ll see yellowsn0w 0.9.1 in the repos. It uses a much longer delay to let your SIM card initialize. If you have problems with 0.9.0, try this one and wait a full minute after you seem homescreen, then reinsert sim card. We need both success and failure reports to tune this across the world, so please be patient (but please also report result!)
2. If you are in the U.S. and are trying this with T-Mobile, you must turn off the 3G switch in Settings. Also if you are good with the command line, you can make it much easier by adding the line -q right after the /usr/bin/yellowsn0w line in /System/Library/LaunchDaemons/org.iphone-dev.yellowsn0w.plist (that’s and advanced tip, hopefully someone will make a boosprefs type of tool for it)
3. No PIN support yet. Remember how we said this was beta? Well we’re still working out the flow for SIMs with PINs enabled. Please disable any PIN you may have on that SIM before trying yellowsn0w, for now..
4. The unlock will silently quit on anything other than baseband 02.28.00. It detects the wrong version and just quits to avoid any damage. Please double check your Modem Firmware setting in Settings->General->About.
