This is from the O2 site
I already use my O2 PAYG sim in my unlocked 1.1.4 iPhone in exactly this way but this sounds like it should work on a legit 2G iPhone now.
Soooo... I'm wondering if I upgrade to the new 2.0 software whether it will work without the need to jailbreak/unlock. Anyone tried it?
I'd be willing to try it as long as I knew I could go back to my unlocked 1.1.4 state if it didn't work! But of course that's the trick isn't it
Already an O2 Pay & Go customer
If you're an O2 Pay & Go customer you can use your current O2 Pay & Go SIM card with the original 2G iPhone. To make the most of the iPhone features, you can add the O2 Web and Wi-Fi Bolt On for £10 a month giving you unlimited browsing and Wi-Fi access**. To add the Bolt On you'll need to either call 2425 free or text WWW to 21300 free. The only thing that does not work with this option is the Visual Voicemail.
