Reasons not to jail break iPhone 4s with sprint?

I know the benefits, but what are some reasons I should not jail break my iPhone 4s with sprint as a carrier. I'm in an unlimited data plan with 5 ppl including myself.

Top reason: Jailbreaking with Sprint will void the warranty.

Don't worry about voiding the warranty. 'Bricking' your device is a thing of the past, it is almost impossible to brick your device while jailbreaking now. Developers spend months developing a jailbreak to make sure that normal people like you and me can use the software and get the job done without it harming our devices. If you don't like your jailbreak just upgrade or restore your iphone on the computer, that gets rid of the jailbreak. The only way it will void your warranty is if your dumb enough to take it in to sprint jailbroken.
