One thing I read was that you can run some apps in RAM as opposed to ROM, but how do you do that?
you can run apps from internal memory or from sd card, depending on how much space you want and where
I would use titanium backup pro, to move to and from sd card
bloatware and get rid of it.
bloatware is a preinstalled system app, freeze don't remove, with 'titanium pro' or 'rom toolbox'
easiest way to remove bloat is install a custom rom, most bloat is already gone
look at cm7, cm9, or liquid roms
[D2/D2G/DX] CM9 Build Thread - Droid 2 / R2D2 / Milestone 2 / Droid 2 Global - RootzWiki
LiquidICS V1.5 [Unofficial port] - Droid 2/R2D2 Development - RootzWiki
official cm7 doesn't work on 4.5.621 so use
cm7 for 4.5.621
GB 4.5.606 bloat list
if you delete a file or app, you have to use .sbf, if you want/need it and didn't backup, and just because you don't think you need it doesn't mean you don't
removing yahoo, can break other email apps, if you froze it it's an easy fix, just unfreeze, and reboot, may need to wipe cache
VZ Navigator was referred to as bloatware on one site, and seeing I use Navigator (that little blue triangle)
yes it's bloat and it's not free, use google maps/navigation or waze, they are free and work better
something through Super Users,
superuser is a firewall, you control which apps have, root access to system files, with allow/deny
use titanium to backup/freeze/remove/restore, and root browser to move files,
