Mislim da je en tip dobro razložil kar se tega tiče:

I think the real reason is how push works. When a push-enabled app wants to receive push notifications, it registeres with Apple's Push Notification Server (APNS). It sends the App ID and the iPhone/iPod's UID to the server. The server does its magic and sends a unique push token back to the device.

Now, if the iPhone hasn't been officially activated with iTunes, but instead "cracktivated", the APNS doesn't recognize the iPhone's UID as legit - because it's not activated after all - and doesn't generate the push token.

I don't think this was done on purpose to avoid people from cracktivating their iPhones, but to avoid abuse (spoofing) and attacks to the server. Yes, someone could make up fake UIDs and talk to the APNS, overloading and doing denial-of-service attacks to it by generating tons of tokens. By only issuing tokens to valid, active UIDs, this is made much more difficult.

So, no Apple conspiracy here, it's just plain network security.

Nisem namigoval, da to počne namenoma, ampak da je pač za tiste, ki imajo odklenjene in crack aktivirane iPhone to nemogoče. To funkcionalnost zgubijo. Zato so seveda iPhoni, ki so kupljeni odklenjeni (recimo italijanski) vredni dosti več, četudi so Jailbreakani.

ko ze govorimo o odklenjenih iphone-ih, se torej splaca kupiti za 600 eur v IT ali ga dobiti iz UK, zaklenjenega, za 500 eur? vedno bolj razmisljam o iphone-u in vedno tezje se upiram nakupu ...

V nadaljevanju debate pa se ugotovi, da nekaterim dela nekaterim spet ne. Probleme imajo predvsem tisti v USA. Lp

Jaz imam 3GS iz usa, pa sm zdej testiral cel dan to zadevo in deluje. A je komu jasno zakaj? Sej se ne pritozujem, sam cudi me.
