iPhone could be more powerful than Nintendo DS and Sony PSP, but the software is holding it back.

Next week, one of the best looking games yet for the App Store will be hitting iPhone and iPod Touch gamers – Doom Resurrection.

id Software lead programming whiz John Carmack, who has developed 3D engines from Wolfenstein 3D to the yet-to-be-released Rage, has been quite charmed by the iPhone since its release, an opinion that he’s not afraid to share.

“I love the iPhone,” Carmack said in an interview withVentureBeat. “It’s a real game platform, not a tiny little toy.”

According to Carmack, the iPhone/iPod Touch has stronger gaming hardware than the Nintendo DS–which should be no surprise–but even stronger than the PSP. So then why have iPhone/iPod Touch games thus far been below the graphical and audio quality of the PSP? It’s a problem with the software, said the programmer.

“If you look at it in raw hardware horsepower, the iPhone should be better in performance than the Nintendo DS and the PlayStation Portable,” Carmack said. “But the truth is, you can’t exploit it all because of software inefficiencies.”

While the Nintendo DS and Sony PSP are purpose built for gaming in mind, the iPhone software must also manage other forms of applications and even (gasp) phone functions.

Escalation Studios, the developers behind Doom Resurrection, expect to be able to take advantage of various features of the upcoming iPhone OS 3.0, though the game is designed to run fine on the current 2.x base.

As with any development platform, the software tools will get better over time, which should yield better games. The only disappointing bit of news for diehard first-person shooter fans is that Doom Resurrection will be an on-rails experience.

iPhone 3G S Pre-Orders All Sold Out

For the last two years running, there has been long lines outside Apple and AT&T stores prior to the launch of the latest iPhone. Some people wait in line for up to a week to ensure they walk away from the shop with an iPhone and don’t end up disappointed when the phone sells out.

Unfortunately, this year is going to be a little different. AT&T has confimed reports that pre-orders for the iPhone 3G S are completely sold out. Customers placing pre-orders now are being told their pre-order will go through but they won’t get the phone on the 19th. In fact, they’ll have to wait up to two weeks to get one. Ouch.

According to Engadget those who placed pre-orders before they sold out will have to stand in line to pick up their 3G S, but are still guaranteed a phone. Or you could chill out, sleep in, and pick your pre-ordered phone up when the queues go away.

Anyone planning on buying the latest iPhone? Unfortunately us Europeans have to wait until June 26 to get our hands on the device.

DataViz brings Documents To Go to the App Store

Editing documents? On a phone? We’re sure most iPhone users are a little taken aback by this prospect, but we assure you it’s completely safe and devoid of artificial preservatives. DataViz just launched its Documents To Go suite for the iPhone, which lets you edit and create Word documents, sync work files with a desktop over WiFi, and view other Office documents with the iPhone’s existing viewer — it’s not the first app to offer some of these functions for the device, but it’s the first with this level of street cred. An optional version of the app also includes a Exchange mail client with ActiveSync for accessing and editing Word documents from email, which seemingly flies in the face of Apple’s vague «don’t mess with Mail or any of our other built-in apps» policy. The basic Documents To Go app retails for a limited time at $4.99, while the Exchange version goes for $9.99 — and anyone who picks up the 1.0 version will get a free update to include Excel editing once it becomes available.
