This is step-by-step instructions on how to perform tethered jailbreak of youriPhone 4 on iOS 6 firmware using RedSn0w 0.9.15 for Windows.

With Apple’s purchase of a fingertip sensor firm AuthenTec for $365 million, there has been much speculation on how Apple might utilize the technology in its future devices. Today Patently Apple reported on a new Apple’s patent introducing an all-new unlock screen feature based on fingerprint technology.
Apple has confirmed that it will not be selling an unlocked version of the iPhone 5 in the U.S. at launch, reports The Verge.
We spoke with several Apple Store customer service representatives today, who informed us that US customers won't be able to sign up for the unlocked variant of Apple's new flagship phone when pre-orders start early tomorrow morning. The unlocked version also won't be available from either the US online or brick-and-mortar Apple Stores when the iPhone 5 launches on September 21st.
According to a report from The Telegraph, Apple will likely discontinue the iPhone 3GS once it introduces the new iPhone at next week’s media event. The report also said that Apple will likely introduce an 8 GB iPhone 4S with a middle price point as it did with the iPhone 4 last year.
“The new update will mean that the 8GB version of the iPhone 4 will be the entry-level iPhone, probably given away free on £20 per month contracts, as the 3GS is currently”.
The Telegraph also notes that iPhone 5 will come in three different capacities, probably the same 64 GB/32 GB/16 GB line seen with the iPhone 4S.
Moving the iPhone 4 into the position that is currently occupied by the iPhone 3GS would allow more carriers to offer a free iPhone, because the iPhone 4 is sold in both CDMA and GSM versions while the iPhone 3GS is only offered in GSM version.
The iPhone 3GS would probably be most missed by customers who want to buy contract-free smartphones. Currently Apple sells contract-free, unlocked iPhone 3GS for $375 in the U.S. and at higher prices in other countries such as $455 in China. If the company elected to continue selling the device along with its three other iPhone models, it would have to cut the price even further.
