Stuck at Reboot??? Help, I need a phone again!!!

[PandaExpress22]

My jail-broken IPhone4 crashed. It was version 4.0. Cydia on it. It won't boot past the white Apple at start. I did a recent backup on ITunes.

Anyway to restore the Iphone4 from my backup and not loose the JailBreak? If I click restore, will that upgrade my phone and block any new jailbreak?

It will enter DFU mode

Please help. I'm stuck without a phone right now.

Thanks so much

If you restore yes it will lose everything it will be like a new phone also when u restore if not using tiny umbrella it will restore to the latest firmware.

Thanks supra1jz. That is what I really don't want. I'm a flight attendant and use the swipe to airport mode all the time. And love the tethering for the hotels that have slow internet. In fact, I am on a trip right now and trying to get my phone running again. Terrible not to have a working phone when you travel. But I don't want to rush the process and loose the ability to jailbreak my IPhone. Slow downloading at the hotel....20 mins to download ios4 ipsw
