Hi! I would like to seek advice regarding this matter: My itouch has a hardware problem (the screen is greenish-white in color and you can't do anything to it, doesn't respond to itunes or to the simultaneous press of home+power button) so I had it diagnosed at Powermac. They advised me to have it replaced bec my warranty is out (replaced costs a 8k and only has 3 mos warranty). I am considering this but at the same time, I'm thinking of having it repaired at Greenhills. I'm afraid that repair centers at Greenhills might not find a solution to it and if that's the case, is it still possible to bring it to Powermac and have it replaced even if I "bailed" my itouch out? Thanks if someone can offer advice on this.
