iOs & iOs Apps (inc iPhone, iPad, iPod, iBrick)

My 4 is the same and has been acting up for the past 2-3 months. The Facebook app in particular is an absolute chore to use now and so I never really log in to it any more..

Does restoring the phone help? Might give that a go this weekend.

I just didn't upgrade! I stuck to 5.1 or something. Hangs with some of the newer apps and I can't even download some, but still works pretty well. If it ain't broke.....
