At the moment there seems to be nothing you can do to get this update over the air other than keep trying.
In the meantime make sure your phone is backed up and all your important data saved by either preforming an iCloud Backup or a iTunes Backup, preferably both!
When you have got yourself backed up get yourself over to iTunes and try the software update from there, it is currently downloading without issue for me and numerous other users are reporting the same…
If you follow my twitter feed or Sony / Playstation or Game UK you will no doubt have seen the fury spread across the internet of foul play, cheating, link sharing and as Sony as so very prone too, hacking! #4thePlayers #notfortheplayers #forthecheats
On 15-19 December 2014 Playstation UK and Game UK ran a competition that meant the first 100 correct entries to this competition got a opportunity to purchase – at full price (£399) – a 20th Anniversary Edition of the console. One of only 13,500 globally, so a very rare item indeed. Well at least that was their plan until link sharing, web site crashing, cheating and hacking took over and left the genuine gamer with no chance whatsoever of bagging one of these much sought after machines.
Allegations flew but facts remain, users (cheaters) ended up with multiple consoles…
You will see from the screen grabs above that this user even claims to be a genuine gamer, but is so very kindly prepared to accepted £3000 for a console (but yet they mean so much to him and he is so blessed) yet towards the end of his posting he is getting rather abusive and showing his true colours!
