Guys, sorry for noob question.

ROM 2.0.9 FINAL aka MAD team vs Eclair (2.1)
- will it solve for problem of running out of internal memory for apps? (FYI i dont have any other game other than angry bird.lol.the rest are just social networking like fb,twitter, foursquare etc)

- how bout battery performance? my current battery life only last for 1 day and half. most of the time when im outside i switch off my mobile network..only when im home, i open wifi
