Anyone experiencing the site being a bit laggy since updating to iOS5? (iPhone4)
I'm finding text input very laggy, the forum taking a while to render (if that's the correct term for text going from a bit blurry to clear). Hence, I find myself double tapping to increase the text size, then double tapping again when it doesn't respond...and the inevitable increase and decrease when the phone actually does it. Text input is always seconds behind the actual tap...as opposed to say, writing a text or email. 
Problem with the forum or with the phone? Is there anything I can do to speed it up? Clear cache? Get rid of the shedload of never-used apps?
(Sensible answers only please...but go on, take the mick if you must) 
Also, one other question (not iOS5 exclusive): why, when switching windows, does the page sometimes reload (but not refresh) and sometimes not?
