I think data2w is all about stability and reduce data corruption (with no life on the edge).. but if you preferred speed you can use data2sd or data2ext.
But data2w + sqlite3 hack is very fast..
unfortunately no sqlite3 hack for gb sense..
We need melethron and ownhere here..
How do I flash the sqlite3 hack? Is it ROM + data2WE + lifeontheedge + sqlite3 in succession, without rebooting in between any stage?
