Hi there, if this title was cover please let me know. Previously i've jailbroken my iphone 4 IOS 4.2.1 I install sbsetting, activator, winterboard, bytafont etc. Of course those i mentioned will eat up some RAM. I remove winterboard after i found it affect the iphone performance, but what i really found is, my available RAM in idle with winterboard installed was 356, after i remove winterboard (thinking it might release more RAM), but end up the RAM goes down to 341 in idle. Why is this happening, aren't it suppose to release more RAM since it is removed? Anyone there can provide any explanation?
