iOS 4.1 Breaks Jailbreak/Unlock, Possibly Forever, Probably Not

As you know, iOS 4.1 will be coming out at some stage today, so when your iTunes prompts you to update just hold back for a second. According to the dev team, iOS 4.1 has a new baseband which breaks the current jailbreak and unlock, there’s no known way to get around it as yet
This means you many not be able to jailbreak/unlock your device ever again! Now the chances are the dev team and other hackers will work out away around this, but it could take weeks and months.

So you need to make the choice,
Do you want the Game Center, HDR Photos, Proximity Sensor and Bluetooth fixes? Or do you want to keep the freedom of being able to jailbreak/unlock your device?
I’ll leave that decision up to you
