yes
the iPhone 5 has been available in store for sale since 12 September, 2012
Wednesday
Proably on launch day. The iPhone has been on Sprint since the launch of the iPhone 4S.
Going by the prices in US Apple Stores as of 7/30/13, the cheapest iPhone 5 would be the iPhone 5 16GB (on a 2-year contract with either AT&T, Verizon, or Sprint) in either black or white for $199.
September 21st, 2012. The sheer excitement!
One can purchase mobile phone cases for an iPhone 5 wherever electronics are sold. Stores which sell electronics also sell accessories. These stores include Best Buy, Radio Shack and Target.
I would have to say the iPhone came out in 2008. After the presentation, Apple releases it in their stores.
Staples is a good example of an office store that should have a case for an iphone 5 in stock. If they do not they will be able to order one and supply it.
The iPhone 4
After Iphone 5 is the Iphone 5s
Yes, most stores carry both the 16GB and 32GB iPhone.
