It seems like my phone is constantly using a lot of ram. Is there anything I can do to free up more to speed my phone up a little? I know that most say task killers are nothing more than battery killers as the apps will simply restart on their own. But are there any task managers, that anyone recommends? I thought I would ask as I always see people saying that they have around 200mb free, whereas I rarely have 100 free. Thanks for any help.
