No problem.
Just for clarity,
This is to sort out push notifications on and unlocked, jailbroken iphone 2g/3g
How it works:
When you activate an iphone legitimately ie. using itunes, the apple servers registers the iphone's serial number and stores it, so when you use a push app, it knows that that particular serial number is your phone's and sends push messages to that phone.
Now when you use ultrasnow to unofficially unlock the phone, your phone's serial number never gets registered to the apple servers so when you use a push enabled app, the server doesnt know who to send the message to.
There are some pushfix solutions on cydia and over the web, what they do is replace your phone's serial with one thats already registered. Do you see the problem with this?
If everyone uses the same serial number, who's gonna get who's messages and notifications?
I've tried the pushfix from cydia, it doesnt work properly, you get random push messages etc from other people cos your ALL sharing THE SAME serial number!
So how do you get past this?
Use a legit registered serial number that nobody else is using.
In my case, i have a friend with a vodacom bought iphone 3g, who bought it "cos it looked cool". He has never installed an app, doesnt know a thing about jailbreaking and has no interest in IM apps and such.. (You may have wives/sisters/etc who fall into this bracket)
I jailbreaked his iphone, extracted his legitimate key, and injected it into my UK unlocked iphone 3g. Voila, perfect working push notifications..
In return I loaded on a few cool apps etc.
If he gets around to using push then yeah, we may end up with each others messages, but by then i'll probably have changed my phone
so yeah, thats the whole process.
use it, dont use it...
