ios 6.1 final
Apple publicly released iOS 6.1 firmware's final build for iPhone, iPad and iPod Touch yesterday. This update contains minor enhancements and security fixes, including: LTE support for more carriers  This final build is released roughly three months after the first beta of iOS 6.1 was seeded to developers only. As far as jailbreakability of your idevice is concerned, read this article for a warning issued by the evad3rs.  


iOS 6.1 Final Changelog :

  • LTE support for more carriers (for a complete list of supported carriers go to http://www.apple.com/iphone/LTE) 
  • Purchase movie tickets using Fandango with Siri (USA only) 
  • iTunes Match subscribers can download individual songs from iCloud 
  • New button to reset the Advertising Identifier

Just to be safe, I recommend you to don't update to this 6.1 update now because it might hamper with your idevice's jailbreakability as pointed out out by the evad3rs. Let's take a look at what the evad3rs have to say for this on the issue of ios 6.1 jailbreak untethered which is still "under construction"
