greenpois0n logoThe Chronic Dev Team have released (site currently down) the Mac and Windows versions of their latest iOS 4.2.1 ‘greenpois0n’ jailbreak. The Linux version is still listed as “Coming Soon”. Jailbreak users are warned to keep their devices on iOS 4.2.1 when version 4.3 is released later in the week, corresponding with the announcement of the Verizon iPhone, as the exploit used in this jailbreak has already been patched.

iOS 4.3 is expected to bring a number of bug fixes, including the addition of “personal hotspot” functionality which will allow users to share their iPhone’s 3G connection with other computers and devices over Wifi.

iOS 4.2.1 Released with Free “Find My iPhone”

Apple has finally released the highly-anticipated iOS 4.2 (actual version is 4.2.1), bringing support for the iPad along with several other feature including AirPlay and AirPrint.

Along with this release, Apple has made the “Find My iPhone” functionality in MobileMe free to all iPhone, iPad and iPod Touch device owners. This service uses a combination of GPS, cell tower and wifi-network triangulation to obtain the location of the device, which can then be mapped. It also allows you to send messages, lock or completely wipe the remote device. To use this feature, you’ll need add a MobileMe account using your iTunes Apple ID by going to Settings > Mail, Contacts, Calendars > Add account. You can then track your device using the Find My iPhone app available in iTunes, or using the MobileMe web interface.

Users concerned about the privacy implications of this feature can easily disable it by going to Settings > Mail, Contacts, Calendar > Select your MobileMe account > Set ‘Find My iPhone’ to Off. Have a look at Apple’s KnowledgeBase article for more info on this feature.

iOS 4.2.1 brings with it a number of security updates (including Safari and numerous WebKit patches). Although it’s not mentioned in the update details, the previously-reported cool-but-deadly keylock bypass vulnerability has been fixed. Hit the jump for full details.
