updating 2g iphone to 3.1.2

I am going to try blackra1n to update my iphone, i usually use pwnage tool or redsnow so this is different and i hope my phone will unlock perfectly. I definitely felt it was time to make the update. My phone has been going slower ever since i updated to 3.0 it was crazy i couldn't take it i felt that apple was just messing with the iphones to make us have to update it every month. When i updated to 3.1.2 I realized that my battery is longer, and the applications open up faster. So if you have an iphone 2g go for it and use Blackra1n!
