My mom went to Maxis centre cos her iPhone got problem, and they asked her for the warranty card (which she didn't have). So she showed her receipt for the phone instead and they accepted that in lieu of the card.

Hi, my 2 cents. There's a difference whether you're referring to the iPhone "4G" or the "fourth generation" iPhone.
- 4G as in, the successor to the current 3G telecommunications network.
- fourth gen as in, iPhone 2G (1st gen), iPhone 3G (2nd gen), iPhone 3GS (3rd gen), iPhone-in-2010 (4th gen).

The iPhone expected to be launched this year (the fourth generation) might or might not be 4G ready, as you mentioned yourself. This is because AT&T is also not expected to roll out their 4G network until 2011 or 2012 (source: macrumors.com). But again, this is all speculation.

In short, yes it's expected there will be a new iPhone model announced in June/July, released in Sept -- but whether it is 4G, no one outside of Apple knows.

Hope that helps

Hi, able to unlock or not depends on the unit's model, firmware and whether it is old/new bootrom. For more info, check out the pinned threads.

As a sad ending to the tale, after Apple started manufacturing these wifi-less iPhones for the China market, the Chinese government relented and allowed Apple to market the wifi-iPhones the rest of the world uses.

But as Apple already started making them... what to do, sell only lo.
