[Q][Xperia E1][Rooting and Ram management] topic

Hey guys, long time no see ;)

I was wondering if this method really works without any bugs http://forum.xda-developers.com/wiki/Sony_Xperia_E1
What root apps you would suggest to download on this device?
Also how can I get as much free Ram as possible on this device. I am getting around 100MB free ram using Clean Master

So far I ve done few tweaks by disabling unneeded apps and the battery seems to hold on pretty good so far
69% it has been running 22 hours 31 min and it still can last 4 days 11 hours on stand by
pretty good I think.

Thank you.
