    I have an iphone 3g running firmware version 2.2.1 that I jail broke with quickpwn a while ago when I first got the phone

    I installed many apps such as bite sms (to hide my sms previews) , swirly mms ( to receive and send mms) ibluetooth ( to send files to other people with blue tooth) winterboard (for a custom background) and a few other apps only available to those with a jailbroken iphone.

    Since then I believe there is a new firmware available from mac witch is far better than 2.2.1

    I have friends with non-jailbroken iphones who are able to send and receive mms, copy and paste, and use mac approved apps that aren’t supported by the 2.2.1 firmware.

    So, I want to upgrade to the latest firmware (3.0 I think or is it 3.1 now?)

    What is the best way to go about this? I assume I should restore the phone threw I tunes then upgrade to the latest firmware then re jailbreak? Or should I not restore and just select to upgrade firmware?

    Will I loose my contacts etc or is this backed up by itunes and resynced or restore?

    Will I loose all my previous apps from cydia etc?

    Should I use quickpwn to do the jailbreak or another application?

    Is redsnow, ultrasnow and yellow snow for unlocking the phone to use sims from different service providers? Or are these other jailbreak programs. I am with optus and only use the sim card the phone came with.

    I have both mac and pc with itunes available to use.

    If you care about unlocking then don't upgrade to 3.1 with iTunes. I would just use pwnage tool to upgrade to 3.1 and you can use something like AptBackup to restore your jailbroken stuff (if it works). If you restore from a backup your SMS and other things will still be intact.
