No problem. Hmmm...not sure. The most pages I've had open at one time was 5 and I was able to flick back and forth between them while within mobile Safari and didn't have any try to reload on me. Not unless you're jailbroken however there is iTunes on the device itself. There's one or two of them. I bought the Navigon app and it's excellent. Navigon (and Tom Tom and several more) all pre-load apps on the device itself. Any one of them has more functionality than Ovi maps does at the moment. Boy don't I know it. I ran up some horrendous charges in Europe, Africa, and the ME. Luckily my employer was the U.S. Government so they footed the bill on their phone chip. You can't....unless your jailbroken. Honestly, I don't play the "ringtone trading game", I just make my own. Once jailbroken you have hte option to download and install FREE ringtones using Cydia. If your friends are also on iPhones and jailbroken they can do the same. Or you can make your own and just email them once done from your main computer. I guess you're not jailbroken? There's some iPhone apps out there for bluetooth sharing, but again I don't do things like that so I haven't researched it thoroughly.
