I would be very careful with this program. There have been plenty of these around for a while. They put a page file on the phone NAND memory to make it look like the phones RAM has increased. The problem with this is the phone is then writing and erasing data quickly to the NAND, constantly. The NAND isn't designed for this and has a limited number of read/write cycles. I've heard problems of peoples phones slowing down several days later and corrupted NANDs. Be very careful with this
