USorry, I have an iPhone 4.
This is the screen I have under Safari Settings:
I have done the clear history and data twice. And my phone has reset itself a couple of times, because the battery doesn't last long.
The other day my son, who's almost two, turned Siri on...I sware I heard Siri say 'Please, for the love of God, just let me die.'
Honestly, I know you guys don't like bugs in your program but I wouldn't put too much effort into trying to solve this for an iPhone 4. It might go away with the next Apple update.
I'll just wait to post new topics from my laptop.
BTW, I just checked and the problem is still there...I wouldn't worry about it.
