I made the terrible mistake of not hearing the storage of the phone when I got it and I have out of 8gb only 5gb left with this huge iOS 8 and now I won't be able to update to iOS 9 and it's terrible am I able to purchase some else's iPhone 5sand switch it with mine without paying a butt load?? it's only been a month?
You can sell the 8 GB 5C for about $200 on swappa, and pick up a good condition 32 GB 5S for $300.
I would not get the 16 GB version , but go with 32 GB at a minimum. It is still very easy to run out of memory at 16 GB. 8 GB is just too small for an iPhone, or really any smartphone in 2015 in my opinion.
