I am trying to replace the power cable on my ipad2, but the adhesive that it came with is not strong enough and it doesn't stay on at all. I was wondering if anybody knows of any other adhesive and/or glue I can use in order to get the cable installed. I want to make sure that it is something that doesn't interfere with the functionality of the cable. I don't want to have to buy another cable (I shouldn't have to). Thanks, Juan A.
