Hello everyone Just had a replacement IP4 from t-mobile as my other one had a yellow tinge to the screen however this one now has a wobbly home button that moves from left to right and up and down ever so slightly it makes a clicking sound as you do this. Screen is perfect however. My other iphones have had a solid home button. T-mobile are being funny saying does it affect performance etc... I said doesnt look to but surely this isnt good on a £500 phone. Am I being OCD or is this not normal?
