Just let the phone get used to the OS6.0. Its normal that the phone loads allot the first few times. It will self solve the problem for you. Do a battery pull and just use the phone let it load after a while it should not load that much anymore.
My phone did the same in the beginning when I loaded the OS6.0.
Btw I almost no free space on my bb ;) and it works great.
I have 37 mb free of application storage and around the 25 mb free of memory
and it works perfectly. Posted via BlackBerryForums.com Mobile
