Great news, jailbreak fans: following the release of a jailbreak tool for iOS 4.2.1, modmyi has been testing out the updated version of Cydia – and they’ve noted that it rocks.

A while back, we told you saurik and chpwn had been working on an improved version of Cydia. Major improvements noted were landscape mode for the iPad, and the addition of a “Sources” tab towards the bottom of the application. After many nights of “burning the midnight oil,” the updated version of Cydia was eventually completed ahead of iOS 4.2.1′s release.

Now, Cydia is included in the redsn0w release. A complete list of improvements has been compiled by modmyi, which we’ve included below.

Here’s a list of just some of the improvements:

  • reduced loading changes time
  • section remapping optimizations
  • faster reloading data
  • faster, native search
  • uses public SDK classes whenever possible
  • rewritten, faster web views with zooming support
  • changes badge works again
  • more stable webviews (no crashes when queueing)
  • redesigned settings page
  • redesigned stashing page
  • faster scrolling of table views
  • bug fixes
  • ads no longer break the package views until restart
  • much better queueing UI
  • stabler refreshing bar

iPad improvements:

  • - landscape
  • - popovesr
  • - modal views that cover only a portion of the screen
  • - less annoying errors with bad internet connections downloading packages
  • - updated section mappings, less typo’d sections

Most importantly, modmyi notes that the new Cydia is much quicker than before – “nearly as quick as the App Store.” This will undoubtedly please a great many users. Ahead of this update, Cydia worked well – though there were times when the app lagged, and sometimes crashed. Now however, this seems to be a thing of the past.

Currently, we’re not exactly sure when iPhone 4 and iPad owners will be able to take advantage of an untethered jailbreak. According to the iPhone Dev-Team, comex is working hard on making this a reality. Though, as of this moment, no time frame has been given.

We’ll keep you posted on the status of an untethered jailbreak solution for iPhone 4 and iPad devices running iOS 4.2.1. In the meantime, you can always use redsn0w to initiate a tethered jailbreak, if you’re desperate to have a jailbroken iDevice. And, as always, let us know your thoughts regarding the changes to Cydia in the comments below!
