iOS 5 will have a new and improved version of Mobile Safari that sports tabbed browsing across all iDevices. Alongside that, Safari also has a new feature called “Reading List” that acts as an Instapaper or Read It Later replacement.
If you sign in on one device, your browsing information and tabs will be transferred across devices.
Cool, huh? Who’s ditching Instapaper? Reading List will most likely only work in Mobile Safari.
