If one created a custom ipsw where it updated the baseband, is ultrasnow usable?
Yes, the whole purpose of ultrasn0w is to unlock updated baseband in iPhone 3.0 for iPhone 3G
Thanks for the quick reply. I must admit, compared to the all the other iPhone info sites, you guys are the best!!!!
Hi Guys,
bit of a problem,I have a foreign sim card not listed but i know the setting for 3G. I have the Iphone 3G OS 3 (7A341) modem Firmware 04.26.08 Jailbreak with redsn0w. No carrier. At the moment I do not have free WiFi but can pay for WiFi in a zone. Would ultrasn0w unlock through Icy / Cydia if I follow the above instructions with this foreign sim card (has no bars for signal and no carrier) using QTel (Qatar) Would it work and unlock the phone? Thanks
yes, ultrasn0w should unlock your phone. Please try and report back so other will also know.
Have a problem. Did the jailbreak and unlock. Took a bit of work, but it’s working here in the Congo (yeah!). But since doing the jailbreak, I can’t sync with iTunes. When I plug the iPhone in, it freezes iTunes (even after unplugging iPHone, iTunes remains frozen). oddly, photos sync with Picasa just fine.
When I did redsn0w, I installed both Cydia and icy. Used Cydia to install ultrasn0w.
Any ideas how to fix this?
Hi Tracy, try the following steps:
1. Launch iTunes
2. Select “Deauthorize Computer” from the Store menu
3. Enter your iTunes Store Account ID and Password, then click the Deauthorize button
4. Next, choose “Authorize Computer” from the Store menu
5. Enter your iTunes Store Account ID and Password, then click the Authorize button
Please report back and let others know if it helped.
You guys totally rock! Yes, that did the trick and the reply was so quick — I sent my question, left the office, and had the reply when I got home. I could just kiss you! Thanks.
Hello,
Just performed jailbreak and unlock on iphone 3g… everything was working fine until i downloaded an application in cydia, dtunes i believe??? but since then i have not been able to open cydia… will not load or it keeps crashing… any solution to fix this problem… thank you…
sorry, never tried dtunes. May be it’s not compatible with 3.0 and this is why things are broke. It may be easier to restore and jailbreak again
Hi, guys.
I want to update my iphone 3g to 3.0 and perform an unlock and jailbreak. Does ultrasn0w work with all modem firmware?
Mine is still on 2.28.00
yes, it does. Keep in mind that people experiencing some minor problems after jailbreak.
Oh okay. So should I wait or is it safe to update and go ahead?
Also, will the update change my modem firmware to 2.30.03?
yes, unlocks modem firmware since it’s what y ou get when you go to 3.0.
Unlock and jailbreak works, minority report problem with stability of the phone.
So you depend on unlock and you are in a mission critical mode, you may better wait for things to become more stable – just in case since you would not be able to roll back to older baseband.
Any other ideas?
I can’t connect a wifi connection here in the philippines,
what should I do to install ultrasn0w without using the wifi connection…
Please help me out…
I’m using windows vista home premium…
iPhone 3G OS 3.0 jailbreak already…
No service~~~
What method did you use to jailbreak. Did you use ipsw file created on mac, if yes you need to make sure that the file was created without activate option on. Assume that you are on 3G
hello,
i am going to europe and am looking to unlock my iphone, but first i must jailbreak it correct? since i don’t have a european sim card to test here in U.S. to see if it worke, does anyone have any experience with this. i don’t want to get to europe and have tech problems. my understanding is all i need to do is pop in a sim card and i’m good to go right? please help, not a techy…thank you!!
yes, you are right. We chatted with users who leave in Europe but have a phone from ATT. the followed this process (yes, you need to jailbreak). With all this things, hope for the best and plan for the worst.
I performed a jailbreak and it worked. Then I proceeded to unlock the phone. Everything worked fine until the last step of powering off the phone and then powering on the phone. A message keeps appearing saying that there is no SIM card even though I have already inserted my Tmobile SIM. Any suggestions or tips on how I can fix this?
Also, it switches from saying “searching” to “no service”.
It turns out I forgot to disable 3G so now it’s working.
I unlocked my iphone 3g but the service doesnt show up
hi will this work all sim card for example ir-mci in iran???
should not be a problem, assuming that iPhone can work on Iranian frequencies.
