Will jailbreak iOS 5? 100% Safe

Many of you wondering now what will jailbreak my iPhone with iOS 5? The answer is already there, remember that the exploit that we use today: Limera1n, an exploit discovered by GeoHot, works at the hardware level, ie can not close, therefore the existing devices (except the iPad 2) may be to jailbreak iOS 5, 6 or 7 ... forever. Just have to adapt to Cydia works perfectly.

There is only one "but", this jailbreak is tethered (tied) until the discovery of a software exploit it untethered.
