Hey all! I've been jailbreaking/unlocking iPhones since the 1g came out - the methods and programs keep changing. I have a 3G with 3.1.2, which I unlocked using redsn0w.

Is this still the process of jailbreaking/unlocking an iPhone 3G with 4.0?

1.) Shift-restore
2.) Load jailbroken/hacktivated IPSW
3.) Turn off 3G
4.) Install ultrasn0w
5.) Profit!

Also, I heard that 4.0 is crazy slow but a hard reset seems to fix that. Is this true?

Close but more like this:

Update through iTunes (official update)
Download redsn0w 0.9.5 b5-5
Download an IPSW
Run redsn0w
Install ultrasn0w
Profit (lol)

The fix for the slow 4.0 on 3G is to disable background image and multitasking (you will be prompted to enable/disable this when your run redsn0w)

If I do an official update, will redsn0w be able to downgrade my baseband, or is the baseband upgrade okay?

If you do an official update it will update your baseband. Redsn0w doesn't downgrade your baseband. If you have an iPhone 3G, iOS 4's baseband is safe and unlockable

Hi I finally decided to take the plunge and upgraded to 4.0 on a 3G 8GB running 2.1 previously. I followed the guide to JB using the link above and then ran the unlock. Now I get no service, but everything else seems ok. Sometimes in the carrier info tmobile and att both show up but I can't make any calls. If anyone could help me it would be greatly appreacited. Thanks in advance!

Did you install ultrasnow and reset your phone?

[unitedef]

Yeah I went into cydia went to sources entered repo666.ultrasn0w.com, installed 0.93, the phone restarted but still had no service. It's strange because the phone tells me I have a voicemail but I can't dial! When you say reset your phone do you mean power off then on or reset network settings? I did both and even the airplane mode on and off and that didn't work. Also I have a universal-sim on my tmobile sim card if that matters at all.

because our iphones are f up. I cant get service either and i tried all the possbile ways. its time for a new unlock. ultrasnow is sht for some of us.

I don't think so, your problems are very rare.

Try restoring and re jailbreaking - make sure you're using redsnow b5-5

sht dont work. already tried it. jailbreakig is not problem. the unlock is.

[adp]

If the unlock had issues there would be hundreds of thousands reporting it. But if you insist then downgrade to 3.1.2 and unlock with blacksn0w

[ozarka]

downgrade to 3.1.2 its not the problem. but my baseband is already at 5.1.3 so blacksnow is not useable.
Done it. Tried it. Already thought ofthis method. Sht dont work. and still wont work.
and using a fuzzyband to get it to 4.26 will not let me install blacra1n
because it needs to be on 5.11 firmware.

More ideas?
