The JB'able betas (b1...3) are no longer signed, which means they can't be reinstalled using the method explained in the previous update. Sorry guys...GREAT news! If you still have iTunes 11.1.3 (or downgrade the current version, 11.1.4, to it – tutorial at http://awesometoast.com/downgrading-to-itunes-10-7-from-itunes-11-on-osx/ , dedicated post at https://forums.macrumors.com/showthread.php?p=18786314#post18786314 ), you can reinstall and activate 7.1b1...3 even now, way after their expiration.Which, while they do have their own share of problems (incompatible JB tweaks like Display Recorder and no support for Lighting VGA/HDMI adapters – see my report at https://forums.macrumors.com/posts/18644744/ . Note that all 30-pin adapters, being passive, work, as is also explained at https://forums.macrumors.com/posts/18647464/ ), still offer way better stability in Safari, particularly on non-32-bit iPads, than the current 7.0.4.See https://forums.macrumors.com/showthread.php?p=18786589#post18786589 for mKTank's step-by-step tutorial on installing these betas.another top tip: https://forums.macrumors.com/posts/18666815/ Now that a solution has been found, I'm rewriting this article. In the meantime, check out https://forums.macrumors.com/posts/18559914/ (Original thread title:and, then,As I've promised at https://forums.macrumors.com/threads/1688110/ , I had a closer look at the possible compatibility issues under 7.1b2, particularly because it's much superior to 7.0.4 WRT the/ Safari behaviour. In addition, I wanted to be sure my own tweaks / apps (see for example https://forums.macrumors.com/threads/1566350/ and https://forums.macrumors.com/threads/1538193/ ) I've updated to iOS7 yesterday are compatible with 7.1.x.Unfortunately,'s advice HERE (also repeated in this very forum quite often; for example HERE ) doesn't seem to work. If you do remove thekey/value pair fromand, after increasing the date to, say, Feb 2014, hard reset the device (so thatis re-evaluated), it'll get into exactly the same reactivation loop as without touchingat all:Did anyone have any success with actually testing the hack with manually-set system dates after applying the hack?NOTE: I've only tested this on an int'l GSM iPhone 5 but not on an iPad or an iPod touch. (Prolly it's the iPad, which isn't in need of phone activation, that other people had success with?) I've tested two times:- first, I immediately changed the date after editing the plist file and, only after that, did I reset;- second, I reset after editing the plist file and only after the reset (which booted in just fine) did I change the date to February, 2014. (Needless to say, the next reset resulted in the activation boot-up sequence, resulting in the need of a full restore.)(at least if you have an iPhone), don't trust this hack - it won't prolong beta2 beyond 24/January/2014. It does not seem to work at all - at least not on iPhone 5's.the hack doesn't work on iPads either (see below). That is, it seems you should not trust it.I've received other reports of the "hack" failing (see below). This all means I was right: the hack no longer works with 71.b2.
