Update added slot for sim card removal on ver 5 only.
Iphone 5 - 5s & 4 - 4s cases, use rubber soft type or standard filament.
If you use standard filament you will need to break the case to remove the phone.
Supports should be generated to properly print the overhanging ports. Meshmixer worked well. Make sure the Open side of the case is facing up when printing.

I have printed this in both solid and soft filament.

to add custom text import or open model extrude cut anything you want. :) or pm me. I may be able to assist.
