Does anyone here know where in Cebu I can have my XDA Mini S AKA (HTC Magician / Qtek S100 / Dopod 818 / Dopod 828 / Dopod 828+ / Orange SPV M500 / T-Mobile MDA Compact / i-mate JAM

The problem on the phone is the internal back-up battery needs to be replaced. Medyo very sensitive ang procedure for replacement. Does anyone know of a place here in Cebu where I can get this repaired? Thanks for the help.
