I cleared up like 10mb of ram from my Rom with this handy little app, WIMR (where is my ram). I deleted some of the unnecessary bloatware that I have no use for-like some of Sprint's apps that I can't use on metro pcs and some wma ringtones. You can delete anything using this app, so be careful...do a backup of your phone in case you delete something wrong and have to do a hard reset.
This app worked good on my touch pro and touch pro 2. Oldie but goodie.
