You can easily have it replaced. Ynzal can do it for you. Last I checked, it was less than 1K including the labor cost. LMK can also do it for you. If you do a little research, you can get info on the Net as to how to replace the battery yourself or even replace the internal storage device with a CF card. Think about it: an iPod mini with 16 or even 32 Gb.
@ericklirios I haven't been to Ynzal lately. Do they still repair apple stuff? I thought their apple certification was removed. Another thing, where is LMK?
Yup i would assume Ynzal still repairs apple stuff... Certification/Acknowledgement of apple doesn't neccessarily mean you can't repair or sell apple stuff... LMK is somewhere in Makati...
