iPhone suffers from the touch disease

<p>After weeks of struggling with my iPhone going all crazy ~ being unresponsive and then go hayweird just opening apps and and and... I took my iPhone in just to hear my iPhone is sick and will have to be repaired with a nice pricetag ... I personally think this is clearly an issue from Apple's side and the responsibilty is with them.</p> <p> </p> <p>Can I please get advise on how we can sort out this problem as I cannot keep up wasting time and not getting the true Apple experience!!</p>
