Is it risky to replace an iphone battery if you are carefull and use the instructional video's on youtube?
Also, on amazon,ebay, ect ect i see these 1600 mAH batteries... They are like 6$. How safe are these? i mean, is a higher mAH harmfull for an iphone 3G?
Apple would charge me 90$, waaaaaaay to much in my eyes
