One of the coolest features of the new iPhone 4S is Siri. The virtual assistant will let the user do all sorts of things using their voice alone. Siri will text for you, find the local weather and lots more. Siri does use the data connection on the iPhone 4S to reach its servers back at Apple though. The heavy use of Siri has reportedly put a big strain on some mobile networks.

Bloomberg reports that data use for iPhones has doubled with Siri. Take the doubling of data with all the new users that the iPhone 4S is attracting, and you get a lot of new data use on mobile networks.

It appears that the promised untethered jailbreak tool for A5 devices is not as close to public availability as we all hoped. A couple of days ago the popular indie developer pod2g said that if we are lucky enough we might get it in a week, but maybe our luck just ran out.

It turns out that the jailbreaking tool for the newest iDevices the iPad 2 and the iPhone 4S that pod2g developed relies on the user having a developers account. And since most iPhone and iPad users do not have such account it is impossible to release the tool for public consumption.
