Just go to http://jailbreakme.com with safari in your iPhone and slide the bar. Jailbreaking your iPhone now just as easy as this…
Why should you do that?
Well, first now it is legal, you can always restore your iPhone if you prefer, and you get cydia, like an appstore with software you will never find in the apple app store, such as my-wi which converts your iPhone into a wifi hotspot using your 3G, or have voip calls via 3G, or have sms delivery reports, or shortcuts for bluetooth, or you name it.
I’ve seen some people reporting that when they did the JB the had issues with mms and facetime. The same people by restoring and applying the jailbreakme again, fixed the problems.
Did it work for you?
