I have had mine for a few months now and have received phone calls all these months and my credit cards are perfect! That's rumour! Buy one! You'll love it! Just make sure it's the right model for your phone. This model I reviewed is good only for iphones 4 and 4S.
not true, yes you can keep credit card in this case..my husband has stretched his to fit many cards and none of them have lost data. The only problem with this case is it has no hole for photos...we did drill on that works thought.
