Apple iPad 3G almost sold out

Stocks of the new 3G version of Apple’s much-hyped iPad, released in the US over the weekend, have almost run out.

The new device adds mobile network connectivity, and comes hot on the heels of the wi-fi only version of the tablet computer, which made its debut on 3 May.

Early reports suggest the device is set to be an even bigger hit than its predecessor.

Analyst Gene Munster from investment firm Piper Jaffray told tech news site Information Weekly he believed Apple had sold around 300,000 iPad Wi-Fi + 3G devices in the last three days, with many Apple retail stores selling out. The weekend’s tally brings total iPad sales to more than a million.

Apple's online store currently reports a waiting time of five to seven days for both iPad 3G and the original wi-fi only model. iPads. The new wifi model is currently selling Stateside for $629 for a 16GB model, rising to $829 for the 64GB unit.

UK fans still have a wait to get their hands on an iPad. Apple promises the device is coming to these shores in “late May”, with pre-orders opening on 10 May. UK prices have yet to be confirmed.
