iPhone 3G lets you talk on the phone while transferring data

Unlike the original 2.5G iPhone, which doesn't allow EDGE data connections while voice services are active, the iPhone 3G allows users to transfer data over the UTMS/HSDPA network while on telephone calls--a significant enhancement.

Apple says:

iPhone already gives you mobile multitasking. But 3G technology lets you multitask in more places--without connecting via Wi-Fi. Since 3G networks enable simultaneous data and voice, you can talk on the phone while surfing the web, checking email, or using Maps. All from your 3G cellular network.

Can you really do multitasking? Switch back an forth through web pages, word documents, calendars and everything? I guess not. How sad.

Wrong, you can multitask with the current iPhone. You might not be able to load new data while talking on the phone, but you can check e-mails that have already been downloaded as well as their attachments, and pretty much any other feature on the phone, including looking up someone else's contact info and then merging a call. Extremely easy.
