iPhone 3GS in short supply as WWDC looms...

There's a few days to go until Apple's annual WWDC event in San Francisco, and it looks more likely than ever the company will use the event to introduce the iPhone 4HD and to reveal more of its wider product strategy.

Earlier this week we learned that the iPhone 3G has been removed from sale with WalMart now offering the iPhone 3GS at $97 with a two year contract instead of the iPhone 3G which previously filled that price point.

This morning we learn that Spanish mobile network, Telefonica, has removed both the iPhone 3G and 3GS from its catalog of available models.

Expectation that Apple will make the new model iPhone available via Verizon remains high, though most industry watchers don't expect to see this until autumn at the earliest.

"I don't expect to see a Verizon-compatible iPhone until early 2011 and that's assuming everything remains equal. Changes to development could push that timeframe back even further," wrote Jim Dalrymple.

So, what can we expect from the next-gen iPhone? Summarising all previous rumours, we may see:

  • Front-facing video chat camera
  • Back-camera has larger lens
  • Camera flash
  • Micro-SIM instead of standard SIM (like the iPad)
  • Split buttons for volume
  • Power, mute, and volume buttons are all metallic
  • The battery is 5.25 WHr at 3.7V, compared to the 3GS battery, which is 4.51 WHr at 3.7V.
  • It measures 4.50 by 2.31 by 0.37 inches and weighs 140 grams

Initial manufacture of 5-megapixel cameras for the device has begun, with Korea's LG Innotek ready to mass produce them starting in the second half of this year.

In another fine feature introduction we also learn the next-gen iPhone will support video chat.

Previous reports have claimed the next version iPhone may achieve 24-million sales this year.
