    I've unlocked my AT&T iPhone 4 using Ultrasn0w and have a new sim card from Optus in Australia. The phone and sms functions work fine on Optus, and I have a good signal (4 bars) and 3G connection. However, I can't get data to work (no internet connection). I'm using iOS 4.0.1 and did save 4.0.1 SHSH blobs. Optus swears the setup is okay on their end. I'm new to this and am not sure what to do next. Any suggestions on how to get the data working?

    You will need to put the cellular data settings into your phone. Have you done it?

    No. I'll google it, but can you provide a link to instructions or explain what you mean in a bit more detail?

    EDIT: I just reset my network settings and now things are magically working!!! Yay! Finally have a jailbroken and unlocked iPhone that is free from AT&T!

    Good you got it working. Optus must have sent the settings to your phone so you didn't need to do it manually.

    If you go to unlockit.co.nz in safari on your phone, you will find a custom profile for Optus, this would have put the settings in for you and may give you the option to put in internet tethering settings too.
