Weborbiter 2.0 runs fantastic on my iPhone 3GS running OS4
I am having a different experience with my 3GS with OS4- although it's very possible I'm doing something wrong. I have mine set to the 480x320 (Iphone) size and Normal Horizontal (3:4). The picture shows up great- no flashing, quick updates, not 5 second reloads, etc and I get the super tux when it's updating, so I know I'm running Weborbiter 2.0.
I am having trouble when I try to click the buttons at either the far right or at the bottom. It seems like the time I hold the button down changes where the cursor would be on the screen. Imagine the cursor starting in the top left hand corner and having to move across and/or down the page to get to the button you want to select. If you were to not move the cursor all the way to the desired button (or in my case not hold the button down long enough) then an intermediate button is pressed. E.g. as I click on "More" from the main UI1 screen, I am often displayed the phone book screen, "Power" gets me to Dial Direct, "Sleeping menu" to "Speed Dial", etc. Sould add that the same thing happens on my wifes 3GS as well.
New weborbiter is a great addition- big thanks to Uplink and Andrew.
