Frankly, you can try the iPhone, it is a very nice and user friendly device, but you may be very disappointed by the lack of usefull applications and the closed system. It's so closed that you can't even transfer a file to or from your N8xx !!!

Still today after the OS3 update, when I compare my boyfriend's iPhone and my N810 ... i'm more thant happy to keep Nokia's device. I can easilly transfer files to and from it by USB or simply by removing the memory card, i have a good spreadsheet, word editing, note taking app ...

If only it was possible to share files between N810 and iPHone, i would have one ... but it's not !

Do you really need to change, you do you just want to spend money ?
