I have had my iphone for a few weeks now, and I really want to jailbreak it so I can install apps and games, but I am really hesitant right now. If I do use iLiberty or one of those programs to jailbreak it, will I lose any features or have any problems with programs that are on the iphone now? Or does everything still function correctly? Is there any downside to jailbreaking the phone at this point, or can I use the pwnage tool in the future to allow my iphone to be updated by apple and still have the latest faetures?
