The screenshot above is from a reader's iPhone 3G. Notice anything odd about it?
Here's a clue: it's running on Vodafone UK.
The iPhone Dev team hasn't released a version of its hacking software that will unlock the iPhone 3G from Apple's official network partner (O2 in the UK). And even when they do, you'll have to sign up to an O2 contract before you leave the store anyway, rendering the unlocking pointless.
Which is what drove this Stuffer to buy an 'officially unlocked' iPhone on eBay from a seller in Germany who claims all German iPhones are unlocked. Sounds pretty dodgy to me, but now that nameless reader (see Jamie, I promised I wouldn't rat you out) can use the iPhone 3G on his Vodafone SIM. Hopefully his company is picking up the bill, because the iPhone sucks down a whole lotta data.
Two words of warning for potential buyers:
1) it's a wild web out there. Just because someone says they're selling an unlocked iPhone 3G doesn't mean they really are.
2) The market price is £500. Which works out at the price of an iPhone plus a year's contract on O2 - including all-you-can-eat data, Wi-Fi subscription to BT Openzone and The Cloud, and visual voicemail.
UPDATE: in response to Lee's comments below I now have another pic (thanks again Jamie)
