which do you guys use to store your contat info. i was using the gmail back up on the droid, but when i got the incredible i set up the back up assistant. not sure which is better, if either. or it if even makes a difference as far as battery life or anything else. i used back up assistant with my env touch and it worked w/o issues. any ideas or suggestions? also if i were to switch from using one to the other how can i change it on the phone? only seems to save new contacts under one or the other and i cant figure out how to switch to the other
