Hi, I want to gift iphone to my mother. She is still using old flip phone. I can get iphone 5 (4 months old) for $410 from friend who is upgrading to 5s, is that a good offer or should I just get 5c? She will be ok with any phone, but she will use the same phone for atleast 3 to 4 year. Considering this is iphone 5 better option or 5c? Cant make up my mind. Any help or input would be great.
