Rom update question

[franco1]

So I've been using the Mighty Rom, and its not too bad. My batter life has increased by around 15%, which is a nice deal. I'm thinking of trying the

MalROM

Can anyone give me a comparison if anyones used both before? Performance wise/battery/speed wise...


And, if I were to use the MalROM, and I have MightyROM on my phone already...Do I just run the MalROM exe and then install it or do I have to do a hard restore or something? Thank you
