so for some time now my iPhone has been acting wierd lately. What I have diagnosed is an delayed/unresponsive accelerometer. For example, when browsing in safari I hold my iPhone vertical then when I want to go into horizontal mode I hold my iPhone horizontal and and it takes maybe 20 seconds or it just doesn't respond at all and then about 2 minutes later it spazzes and by that time I don't want it horizontal. I know it isn't froze because I can still scroll up and Down. It is the same case for iPod and xplane. At first I really didn't care but now it is irritating. And I have reset it and still didn't improve. Should I take it in? Also if I do which one should I go to apple or best buy(I have the $15 coverage plan)?
