today my brother and i went to the mall to buy a new lighting cable, we stop at a stand in the mall just for pricing and cases, when i asked the guy how much for his chargers he asked was i on 7.0 or 7.1, i thought that was strange being as though i just needed a charger, he explains that some chargers dont work on 7.1....i didnt believe him so my brother still has 7.0 he tried the charger in his phone and it worked, once placed in my phone it didnt work at all...has anyone experienced this? that is crazy..is this another way for apple to force people into buy their product?
