I'm also using MemoryUp Pro 2.7,I don't know it really does something?!
I have a huge list of Apps:
iBerry Neo Zen
11.Memory Up Pro
12.My Secret Diary
23.Pocket 12C SE
My Free Mem used to be 22-23MB,my bold works great without any sluggishness!
I don't know whether settings need adjustment and real boost of MemoryUp Pro 2.7
Share your feelings!!
