"something stuck in sim card slot"に関する回答Yikes! Sounds like you have a problem! Depending on the size of the object there are 3 possibility's... 1. Your SIM slot is damaged and you probably should see an Apple pro about it. 2. The object has been lodged in the SIM slot. 3. The piece is a protector of the SIM slot. The most likely of possible things is #2. Your iPhone may have a broken or damaged SIM slot. Hope my answer helped at all!!
"Home button doesn't work when glass is secured to frame"に関する回答Um... The cable is not the problem I do think it may be the iPad's sensitivity that's causing the button to malfunction... You may have internally damaged it some how. Sorry if I am not much help but I do think it's probably not fixable. Your iPad may have a manufacturing fault that's just not replaceable. If you still have a warranty you may be able to get it fixed free of charge. Sorry! Hope I was a bit of help!!
"Rear casing is magnetized, Is this OK?"に関する回答No. As most computer screens... color and coding can be messed up by magnets. The same is true with portable devices. However some internal damage of your device could be possible. In other cases (pun ended) your device may be safe... ish. The cases we have now do many things so if you bought the case from a trusted company... Apple persay, you should be fine!!
