Source is not getting added. Is it ultrasnow.com or ultrasn0w.com ? When trying with ultrasn0w.com I get an error – did not find repository. When tried ultrasnow.com system is giving http://repo666.ultraslow.com sub-process/bin/zip2 returned error n updating sources shows downloading packages and no progress is happening.

Guys… i guess im the only one who upset about this breaking news. i have an iphone 4. but it wont go to homescreen. its required the original owner to activate the phone because the itune ask for billing zip code and 4 last digits Social security number. i dont have all of that. i try to use the phonebook sim and it still wont go to homescreen. im really upset now. i hope the DeV team will help me.. thanks

Ordinary_guyz August 5, 2010, 7:06 am

How can I jailbreak it if the jailbreakme only works with the activated phone?

Kaizoku August 6, 2010, 8:55 pm

I thought you just need a at&t simcard, for 3gs atleast.

moe August 5, 2010, 6:11 am

i have jailbreaked my iPhoine 4 (at&t), then i went to cydia and i added the source :http://repo666.ultrasn0w.com , BUT im getting only ultrasn0w 0.93 for 3g and 3gs not ultrasn0w 1.0-1 for the iphone 4 and all iphone’s.
i tried many time and i installed ios 4.01 and made the jailbreak and restarted my iphone , but im always getting ultrasn0w 0.93 NOT 1.0-1 , can anyone help me with this problem ??? is it activation problem?

tim August 5, 2010, 6:52 am

word over at CNET is that Apple is ready to push another firmware (4.0.2?) … it’s unknown whether the basebang will remain the same or be updated

How can i use the T-mobile Sim in form of microsim due to the iphone4’s sim slot is for microsim only ?
Please give me possible steps to cut down the orginal sim to microsim.
Thank you a lot for all of your help!

Ryanu August 5, 2010, 1:56 pm

I think u need to cut ur sim to micro sim…I think one of the deva did it..I’m not sure who..either sherif_hashim or planetbeing..go and look at their Twitter acct

MpNoon August 6, 2010, 2:22 am

I got it! BY myself … hahhaha
It’ very successful. Just place the orginal ATT microsim on the T-mobile sim, sketch the shape into the T-mobile orginal sim, and cut it. Just make sure don’t cut the chip, and remaining the position of chip respectively.

Thanks,

KalinkiOne August 11, 2010, 3:23 pm

I have installed ultrasnow for my iPhone 4 and my battery life is shorter. 🙁 Have someone any problems with iPhone4 and ultrasnow?

Jic August 12, 2010, 8:40 am

KalinkiOne … yep i can confirm to all people who complaining to Apple for the Iphone 4 battery life. That’s not Apple it’s ultrasnow, we are actually to friend with a Iphone 4 which has been unlocked via ultrasnow and two other friend who has a factory unlocked and my conclusion ultrasnow it’s the problem. Our friend laughing at us because their iphone can last for a couple days even if they use 3g etc …. Mine last only for a day, they asked me how to jailbreak, i told them to use jailbreakme. Call me back 1 hour later telling me their battery doesn’t last has it should be. I told them to remove ultrasnow because it’s automatically add during the jailbreak and they don’t need that cause their iphone are factory unlock. So now everything is fine now for them but all people with ultrasnow still have the same problem, i hope the ultrasnow update fix the battery problem.

Thx … ^_^

ellie October 3, 2010, 5:22 pm

Go back to the older version of ultrasnow. 0.9.3

Jic August 14, 2010, 10:23 pm

Everything work when you unlock the iphone, but i did have a issue yesterday on a AT&T iphone. I activate it but as soon i insert a different simcard it desactivate it and a message appear : the card you insert is different that the one you use to activate your phone, reconnect to itunes to reactivate. So useless, i don’t know if i’m the only one who experience that ? Or maybe it’s a new kind of anti-hacking from apple server. I did activate then jailbreak and unlock and as soon i put my operator sim card it desactivate the iphone but i can see on the top left corner my operator and the signal but useless because the phone is on emergency call. I never experience that before and don’t want to try on another iphone and to be stuck on the emergency call. Anyone has this problem ?

grandelelo August 16, 2010, 1:59 pm

hi every one im from Mozambique Africa…i using 3gs i was stuck in emrgency call, i didnt have the at&t but for luck i tried one vodacom sim and it activated thats the only sim card that is working… i was on 3.1.3…im now on ios4…i did all the jailbreakme prossess, i have Cydia, i installed the ultrasnow 1.0.1 & 1.1.1 to try another sim cards but didnt work….can some 1 help me.

Hi! Alright, so I have IOS 4.3.5 and have jailbroken my phone but can’t seem to unlock it using this program? Is it that the firmware is too recent? Do I need to revert to an earlier version? Is there a different unlocking app I can use? I really don’t want to get a new phone while living abroad!
