I am looking for a simple translucent tpu style case for a 5c for my mom. I used the Incipio NGP for my iP4 and loved it... Is this still a decent case? Will the clear "frost" color get yellow? Or is the translucent grey a better choice? Is the lightning cutout big enough for 3rd party cables? The image on the website is tough to see and I've not seen one in real life... Thanks!
