With the announcement of iPhone 6 today (9), Apple lowered the price of previous models of the device worldwide.
The devices found in Apple's online store are now at more attractive prices, starting with iPhone 5S, found in versions 16 GB and 32 GB per R$ 2.199 and R$ 2,599, respectively and in the colors Silver, Gold and Space Grey. There's still a 10% discount on the spot purchase.
The iPhone 5C now costs R$ 1,499, but only the 8 GB version left on the site. The colors remain: white, pink, yellow, blue and green. There is also a 10% discount on the spot purchase.
If you think it's still worth it (I don't!), there are still 8 GB iPhone 4S units being sold on the official website by R$ 1099.
