I previously had this question with a different title but people couldn't keep their personal comments to their selves (rude much?). Should I unlock and jailbreak my iPhone 3G? The warranty ,according to Apple, expired as of February 2010 and it has been running relatively slow lately after the 4.0 update. The 4.0 update didn't really include anything good for the 3G so I would like to access some of those features by jailbreaking it. What are the pros and cons of doing this? Are there folders like in the 4.0 update? Thanks to everyone who answers.
