Apple is obviously looking to get more people to switch from older models of the iPhone to the latest iPhone 6 and iPhone 6 Plus.
The company will now offer more for your iPhone if you trade the device in at an Apple Store, the promotion is apparently being run this month only.
If you trade in an iPhone 4S you will get $50 of store credit, they previously gave $35, an iPhone 5 will get $100 worth of credit, this is up from $85 and an iPhone 5S will get $200 of credit this is up form $175.
This will only apply in the US, it doesn’t look like Apple has increase the trade in prices for the iPhone in other countries.
If you are looking to trade in your iPhone, you should also have a look at what other companies are offering, as Amazon and other companies may offer you more for your old device than Apple.
