M8MAN make sure you have the latest software update I think for the 3gs its 4.0.1 it made viewing this site easier. I can view pics and post with no problem where before it was a really flaky interface with safari.
Actually, they released 4.0.2 last week, but that has nothing to do with how the site is viewed. It was just to patch a security hole. As far as safari, the JD site has viewed the same for me on every OS since 2.1. Just have to learn your way around the phone & settings. M8, any questions let me know. I should be able to help with most ??'s I'm training my wife now as I gave her my 3GS when my iPhone4 came in and unlocked and set up my friend to use my old 3G on T-mobile. I'm no fan of Apple's propietary system, but there's ways around that & it's the best device out there if you know how to use it and I've used them all, including Droids (great devices, but still 2nd place).
A couple good tips for the JD site are:
1.When you're on any screen, double tap and the screen will fill with that section only (see pic), cutting out ads & top bars, etc.
2. If you want to bookmark JD pages, you have to navigate to the page, then go to "History" and re- open page from the History link and bookmark that. if you don't do that, it will always take you back to the "enter" screen.
