I read on the internet that iOS 4.3 with armv7 is the lowest you can go if you want to support iPhone 5. So, if I want my app to run on iPhone 5, then do I need to set the deployment target as iOS 4.3 and set the architecture as armv7?

I couldn't find an official documentation for this. Could you correct this information if it's wrong?

**UPDATE:** I've found the answer in the [Xcode 4.5 GM seed Release Notes](http://adcdownload.apple.com//Developer_Tools/xcode_4.5_gm_seed/xcode_45_gm_seed_rn.pdf) documentation of Apple:

Changes in Xcode 4.5:

> 
> **- Support removed for armv6**
> Xcode 4.5 and later does not support generating armv6 binaries.
> 
> 
> **- Minimum supported deployment target is iOS 4.3**
> The minimum supported deployment target with Xcode 4.5 or later is iOS 4.3
