Hey now! I'm very close to JailBreaking my 1st IPhone ever but I still have some questions I need answered before I make the leap to do it........ Do the JB programs take up much memory/space on the IPhone 3g V2.2? How many kb/mb are they each? Also, I've read others' posts and I'm curious if a JBed phone has more of a "lag" compared to a stock one? Please let me know, even if it is a minor one. Thanks for the help!
