I helped a buyer send his kaputed iPod touch to Axis Computers in PJ (around a month back), which is just 5 minutes drive from my office in Paramount Garden... His unit can be switched on but the slider is KO'ed...

Service was good actually, i sent the unit in on a Monday and they called me the following Thursday and informed me that the new unit can be collected... Apparently the warranty claim resulted in a one-to-one replacement of the faulty iPod touch, bravo!
