I actually wonder though, with the iPhone's Safari you can have several tabs. (Well not in the traditional sense but like several windows of Safari) I think.Wouldn't it be better to have that then the current implementation of one app for one purpose (ignoring the multi purpose apps like the ones that integrate Twitter, IM, and Facebook Status). That way you could leave one window on Facebook, one window on whatever, etc..

Kinda like a Palm Pre multi-tasking but instead using the browser?
