I'm killing some time in class by surfing for stuff for my phone, and I came across the Seido website. I have friends who have used their products before and I know they are quality. But has anyone tried the 1600 mAh extended battery? I know the battery that comes with the phone is a 1500 mAh battery, so I am not sure how much more battery life would come from this. I know there is a 3000 mAh battery, but in my opinion that kills the form factor of the phone too much for me to warrant even considering it as an option.
