I just installed an iPhone app that makes scrolling SDMB threads way easier.
It’s called QuickScroll and it’s available for free in Cydia (you need a jailbroken phone for this) under the category System.
I can scroll right to the posts I want to read in a long thread without having to keep flicking the screen to scroll all the way down to last few posts of a long thread.
It works in any app, but I find it most useful in apps that need lots of scrolling. Like Safari, Cydia, and any other app with a long list.
QuickScroll does not install an icon on the iPhone. To access the settings for QuickScroll, go to System/QuickScroll.
I’ve been using it for a day and it’s very stable.
These settings seem to work best:
Tapping: On spot
Activate by: Scrolliing
Disable for: All, except the ones you think need it
