Apple is finally letting you buy a factory unlocked iPhone 4S directly from their website. I believe this is a much better deal if you are not eligible for an upgrade and are looking for a good resale value when you are ready for the next best iPhone! I would buy it online for some cashback and the convenience of the iPhone being shipped to our doorstep.

There is a catch though – it is a world phone but limited to GSM worldwide.
How about some cashback?

When it comes to iPhone purchases, not many …

iPhone 4 was recently jailbroken and now it is unlocked too, thanks to the Dev Team. It cannot be easier, no PC/Mac required, only the internets!
All you need are the following :

A Jailbroken iPhone 4 / 3GS,3G (it should be activated, that is a pre-req for online jailbreak)
A WiFi connection
That is pretty much it!

Step by step (best practices) :

Launch Cydia and search for ultrasn0w [if not found, then add repo : repo666.ultrasn0w.com in Cydia]
Install ultrasn0w and reboot your iPhone 4 when prompted. Turn 3G off  (Settings -> Network -> Enable …

For a list of important Cydia apps and more screenshots, go here. Visit this page if you have an iPhone 4.
There is not much to write about this time around (no PC or Mac limitation)! Jailbreaking is perfectly legal btw!
All you have to do is :
- Make sure your iPhone is activated. It is not possible without a valid iPhone SIM. If you don’t have one, we must wait until another tool is released.
- Make sure you sync your iPhone to iTunes. This is important, just in case you know!

Original iPhones (metal back, silver color, referred to as 2G iPhone) are blessed with a fully unlockable baseband 04.05.04_G. It entitles the iPhone 2G to be easily hackable. So lets get the ball rolling and get to the latest 3.1.3 firmware with a full unlock, jailbreak and activation in place!
Step by Step :
Download redsn0w 0.9.3 from downloads section and extract them to your Desktop [Both Mac and Windows versions of redsn0w are available there]
Connect your iPhone 2G to your PC/Mac and launch iTunes [Update iTunes to the latest version]

Update to …

Geohot released blackra1n (jailbreak) and blacksn0w (unlock) for the latest firmware/baseband combo on 3G and 3GS iPhones for both Mac and Windows platforms!
Features of blackra1n RC3 :
- Jailbreak / Unlock
- Hacktivate or legit activation
- All Macs (Intel and PPC) and windows
- (Possible) Tethering option enabled

UPDATE : If you have 3.1.3 iPhone 3GS + 5.11.07 baseband and if blackra1n doesn’t work, try blacksn0w RC2 which can be installed by adding http://cydia.pushfix.info into Cydia sources. Please post a comment if you still have problems unlocking your 3GS.

Step by step instructions : …

Geohot did it again – the impossible! He hacked into Apple’s most secure baseband till date – 5.11.07 is now successfully unlocked and will be ready for general consumption come November 4th, 2009! He gave us 3.1.2 all device jailbreak and now blacksn0w! This kid sure is awesome – all props to Geo, the man!

iPhone 2G, 3G, 3GS users can now safely update to 3.1.2 firmware without updating the baseband (for unlock). If you are not the one to download all the various files and just want the ultimate result, these files are waiting for you to download! If you rather want to start from scratch, download Pwnage 3.1.4 tool for Mac.

Caution #1 : A restore is going to wipe the iPhone clean. Hence, please backup your iPhone using iTunes and then proceed.

Apple released 3.1 with not so many feature enhancements. Please refrain from updating either iTunes or iPhone firmware using automatic updates. These will soon be patched for continued jailbreak and unlock support.
If you update, you may permanently lose any chance of unlock (atleast for months!). The following screenshot by Musclenerd of Dev Team fame proves that baseband for iPhone 3.1 can already be preserved. So, sit tight and wait for an updated firmware or better yet, pwnage tool to tailor an ipsw yourselves!

UPDATE : The following guide holds good only for iPhone 3GS 3.0 firmware. For 3.0.1 use redsn0w guide instead!
Geohot has done it again! He gave us the first jailbreak for iPhone 3GS and now, we have a much more efficient iPhone 3GS unlock – purplesn0w. Seriously, all the sn0w versions are confusing but well, that is their game!
For now, the iPhone 3GS should be activated using an official carrier before purplesn0w is installed on your iPhone 3GS. (Hacktivation for other carriers to follow soon)
Why is this unlock (purplesn0w) more reliable …

So you used purplera1n and jailbroke your iPhone 3GS but you still see the emergency screen huh? We just have to hacktivate your iPhone and then we can unlock your iPhone using ultrasn0w!
Lets get started :
1) Make sure you used purplera1n and jailbroke your iPhone 3GS. If you see the Emergency calls screen, you may follow the next few steps.
2) Download this lockdownd file.
3) Download iPhoneBroswer for Windows. You may try PhoneView for your Mac.
4) Launch iPhoneBrowser and navigate to usr/libexec folder as shown in the picture below. (If you …
