Saxxat från iphone dev team’s blog:
“Warning: If you care about the possibility of a GSM/3G unlock in the future (there is no unlock available as yet), do not update your 3G device with iTunes unless you do it via PwnageTool 2.0.2 (this means you’ll need to create a custom .ipsw with PwnageTool 2.0.2 and install it using iTunes) – If you have updated over the last few days with iTunes, you’ll still be able to Jailbreak using PwnageTool 2.0.2 but it may reduce the chance of you being able to unlock the Phone to be able to use a SIM card from all carriers in the future.
To clarify – PwnageTool 2.0.2 will still provide the jailbreak for 3G users, even if you have updated. Meanwhile, we’re still actively pursuing the GSM/3G unlock – stay tuned.”
Jag uppdaterade till 2.0.1 dagen då firmwaren släpptes, kan jag på något sätt hoppa tillbaka till 2.0 då jag gärna vill kunna unlocka min iphone 3g i framtiden.
