“Siri, how much data do you gobble up in a month?” Ars investigates

Apple’s new iPhone 4S has been in users’ grubby little hands for a bit over two weeks now. One of the main features of the 4S is the virtual “personal assistant” Siri, a technology that Apple acquired in 2010 and integrated into iOS 5 for integration with the iPhone 4S. When we put Siri through its paces during our iPhone 4S review, we came away with a mixture of bemusement and optimism. The service is still in beta and has its rough patches, but it’s pretty decent at performing Web searches and other basic phone tasks, such as setting up appointments, making reminders, and text dictation.

But one huge caveat to Siri is that it requires an active Internet connection in order to function. Apple sends Siri voice data up to its own data centers for processing and the sends the results back down to your phone, even if you’re only trying to perform a task that shouldn’t require any network connectivity. This can sometimes be frustrating when you’re in a low-signal area with no WiFi avail
