Urgent Help!!!

[trololo145]

Hello Brighthand, I need a lot of help.

I just bought a second hand Iphone 3g for my mom for christmas. It is locked to fido, she is on telus. It is running firmware 4.2.1

Since it doesn't have a valid sim card in it, it won't let me use it. The only function is emergency call.

Here is what I would like to do to it:

Jailbreak it, unlock it, then reset it so it's unlocked without any jailbreak. Once that's done I want to downgrade the firmware to a lower version (optional but would be appreciated) because 4.2.1 is very slow on the iphone. HOW CAN I DO THIS? Can you jailbreak unlock then reset it and still keep it unlocked??!??! help!

Have you tried a Google search? I just did, and while there are many, many hits, I can't positively or negatively recommend any of the 'how-to jailbreak' sites. Good luck, I hope someone comes along to help soon.

Not positive about this, it has been awhile since I was JB, but I think you have to have a SIM in it to get started. Try these two things. First, have you just plugged iPhone into iTunes to see what happens? That would be the ONLY possible way to download any software without a SIM. Two, can you get an old SIM just to stick in there to get the phone working? Does your Mom have the old SIM anywhere?

I know that's not alot of help, but it is all that I know to do right now. I highly recommend you go to TiPB.com and read through their JailBreak section. TONS of great information on JB "Do's and Don'ts" I would read as much as possible first before I started!

I believe getting into DFU mode doesn't require a SIM but I'm not positive about this as I've never jailbroken. I really should find the time to jb one of our old iPod Touches just so I know how it's done.
