We noticed iPhone 6 Plus and iPhone 6 back in stock in Apple Store in the U.S. The company finally has enough smartphones to ship in only 1 business day. This is the first time from the official seventh-gen models public release when the Cupertino-based giant is eager to ship the purchase so soon. The news about iPhone 6 in stock in USA is great for anyone who hasn’t yet purchased the gadget in 2014 and is eager to get it in 2015. All variants are currently in stock and the high demand for the cell phones is finally caught up by the ‘fruit’ company. Apple has also began to sell unlocked SIM-free iPhone 6 and 6 Plus and both versions are also available with 1-day shipping estimate. If you think that these models are the same as T-Mobile’s version, you can learn the difference between SIM-free unlocked and T Mobile iPhone 6. All locked variants are also sold with fast shipping option. You can purchase Sprint, AT&T and Verizon iDevices from Apple Store and later unlock iPhone 6 through factory IMEI safe service or buy the SIM-free model right away. Some customers are eager to pay more at once, while others are ok with getting a cheaper gadget and later paying some price for getting rid of carrier’s restrictions and being able to switch between networks with ease. Apple had hard times when high demand for its new smartphone was outstripping supplies. It has finally improved the situation in the market and all customers who want to own this device can use their chance now. Here is how to set up a new iPhone 6.
