Hi everyone, firstly apologies if this question has been answered or asked hundreds of times before but i cannot find a decent and complete answer to it. i have been wondering about removing the black plastic cover from the iphone to clean the speak grills on the bottom, however most of the how-to's and guides etc are all very vague about removing the cover. things they do not mention are - is the cover glued on at any point? - is the cover re-usable or do i need a new one. - how do i replace the cover does it need to be glued, nailed, duct taped etc. - all the usual questions about removal and replacing the cover with no long term effects. again sorry about posting this question, especially if its in the wrong part of the forum. i have spent time googling and as mentioned all the results tend to be a little blurry on the details, and i am just looking for some clear cut answers.
