Need help urgently to reset & restore

[drb99]

Hi,

I'm a relative iPhone newbie but need some urgent help. I have an iPhone 2G 8Gb with 3.0.1 (jailbroken & unlocked).

I've been happily installing apps etc for the last week and everything has been fine. However today I installed an app called MyProfiles (from RockYourPhone) and it has screwed up my phone big time.

It basically won't ring any more, regardless of ringer settings etc, and goes to voicemail after about 20 secs (no ringing sound when calling it either).

So, in short, I need to re-install 3.0.1, jailbreak & unlock it, and then restore my apps & contacts.

Can someone advise me of the easiest way to do this?

I believe Redsn0w is the preferred method (PC, not Mac), I'm reasonably technical (I build all my own PCs etc) but just need some help with what to do, in what order etc.

Oh, and I need to get it done by 6pm tonight!

Thanks in advance..

Just do a restore from iTunes, that will wipe the phone back to a stock 3.01, then download 3.0, redsn0w and re jailbreak
