Pod2g's "Corona" untethered exploit for iOS 5.0.1 gives a new lease of life for the jailbreak community, as the advent of iOS 5 brought a dead-lock situation for iOS users. Thanks to Pod2g, users can now exploit the seamless potential of untethered jailbreaks on iOS 5.0.1. Although the tethered jailbreak was available right from day one of the new iOS software release (both from Sn0wbreeze and Redsn0w), the worldwide community of jailbreak users yearned for a full-fledged untethered exploit for a seamless experience using third-party apps and tweaks.
Until this new release, Pod2g's exploit only applied to devices running on the A4 chip and even older devices - original iPad, iPhone 4, iPhone 3GS and iPod Touch. As a result, most users clung to iOS 4.3.3 or previous versions to enjoy the freedom of untethered exploits from Comex or the Chronic Dev-Team. However, now those users can join the party with millions of other iOS users exploiting the power of Notification Centre, besides over 200 new features and enhancements, according to RedmondPie.
On the eve of its two-year anniversary, Sn0wbreeze, the popular Windows-only jailbreak utility for designing custom iOS firmware with preserved basebands, gets an update to jailbreak untethered. That is a big respite to free users from the hassles of connecting to the computer and rebooting after every update or every instance of installing a jailbreak tweak.

If you are looking to unlock your device for multiple carriers, most of the newer basebands are tough nuts to crack. So, an ideal solution is to preserve the older basebands in order to use your iOS devices with unauthorised carriers. Nevertheless, users who want to unlock their device on older basebands can do so using Ultrasn0w 1.2.5 posted here.
