Warning: Hindi ako mananagot at responsible sa ano mang mangyari sa unit mo, bago mo pa man i-jailbreak ang device mo dapat alam mo na ang maaring pinsala o kinahihinatnan ng mahal mong gadget. ;D


iPhone 3G users if you rely on ultrasn0w to unlock your device upgrading to 4.2.1 will render your phone locked and you need to upgrade to iPad baseband 6.15 to have your device unlocked again thus rendering your GPS useless and always requires a custom firmware to upgrade and downgrade your device even on an official firmware. However if want to take the risk feel free to use this guide.


Ang guide na ito ay para sa mga iTouch 2G and iPhone 3G users na nais mag-upgrade sa 4.2.1 firmware which is the last firmware for both devices and wants it jailbroken.

Pros

- Great selection of app compatibility, from games, productivity, etc on App Store and Cydia
- Final release supported on second generation devices (iPhone 3G and iPod touch 2G)
- Fixes intermittent Wi-Fi issues
- Find My iPhone location feature is free for this version
- AirPlay (replacement of AirTunes, AirPlay will offer stream video, music, and photos over Wi-Fi)
- Improved Battery Performance
- Security fixes
- Able to create folders to organize apps

Cons

- No multitasking and homescreen wallpaper compared to other iDevices like iTouch 3g/4g and iPhone 3GS/4 (can be enabled through JB)
- Slow and animation lags all the time when Multitasking and homescreen wallpaper is enabled.

Why use 4.2.1?

If you are stuck in your old firmware like 3.1.3, 4.0, 4.1, you are now missing some great apps which requires 4.2.1 at karamihan ng mga cool tweaks sa Cydia requires iOS 4 at least just to use them. Now, if you upgrade to 4.2.1, I strongly suggest not to enable multitasking and the homescreen wallpaper, as well as the unified iPod and battery percentage, because it will really slow your device. The good thing about having 4.2.1 is that you can tweak the firmware to make it fast on your old device, make it responsive, and still enjoy the goodness of the firmware.

Requirements:

- iTouch 2g / iPhone 3G
- 4.2.1 OFW firmware
- redsn0w 0.9.8b4 - iTouch 2G / iphone 3G (iPhone 3G user, factory unlocked can use this version no need for iPad BB 6.15)
- redsn0w 0.9.6rc16 - iPhone 3G

- Windows XP/Vista/7
- Internet Connection
