Since I have never officially activated an iPhone, I dont know if what I am thinking of is even possible, but these are my thoughts:


- The push fix works using keychains from officially activated devices
- I would guess, the keychains on those devices are being calculated during activation by using at least at some point the hardware id of the given iPhone
- Because with the push fix, several iPhones have the same certificates, the Apple Servers push msgs to the wrong device

- I am thinking about getting a locked iPhone very cheap, however, if Push doesnt work, thats no good

Now my theory:
- What if I were to put a sim from an official carrier (friend of mine is on t-mobile iphone contract in germany) into the phone, activate it, backup the keychains, then put my sim in and hacktivate the device, copy the keychains back
- At least in my mind, no other device should have the same certificate, and everything should work properly

Any thoughts on this?

thats a more technically stand point from what i was thinking.. if push is seated into activation then use an old SIM from the officialcarrier, if you have one laying around...

or

maybe theres a way to make the keychains using the SIMs we end up using in our phones, cuz if you copy the keychains wont that cause your friends phone to get the push data too regardless of even if their phonewill work with it

Here's what I tried on my 3GS - and it DID NOT WORK (fyi)

I got a locked at&t 3gs, put in a unactivated at&t sim, itunes came up and iphone said waiting for activation. I then installed ultrasn0w and restarted iphone said iphone activated, but push STILL doesnt work.

you need an activated SIM to actually activate your device then it will receive the proper keys etc and will have a officially activated lockdownd then install ultrasn0w and use what ever SIM you want. This works but you will need to use at least one push app and youtube with that official SIM.

Anyone feel free to correct me if I am wrong...

So if I bought a pay-as-you-go iphone & sim-card (say iPhone from Applestore online @ £400, PAYG sim from O2 for free), activated the iPhone with iTunes and the O2 sim, I could then install the ultrasnow program, jailbreak and then use my normal non-O2 simcard?

That would be a good work-around for the push problem with ssl certs!

Yes. You just have to activate the phone with a valid SIM, from an official carrier that iPhone is locked to, then run redsn0w and add ultrasn0w.

PUSH will work just fine.

Aaahhh... So the trick is to go all the way through the activating process with a working official carrier sim (I'm in the USA so in my case, an AT&T sim card).

Now, let me ask this - I have a friend who has a "legit" activated AT&T sim and iPhone, if I use his card to activate my phone, will we get each other's push information? him get my IM's and/or me get his IM's? etc..etc..

That might happen.

But I very much doubt it. The activation token is based on both SIM and SN afaik, so I'd guess that there should be no problem with using a friends AT&T SIM. Why don't you give it a try? Have your friend and you both attempt to use push while your phone is activated with his SIM and then unlocked with your own SIM installed. Seems like there should be no problem imo.
