I would really love for Phojo to be able to run on the iPhone. The OS is definitely up to Phojo’s specs, but the hardware is missing some crucial features. Like a card slot In fact, compared to state of the art Pocket PC Phones, the tech specs for the iPhone are actually a little disappointing. The 320×480 phone is half the resolution of the screen used by the HTC Universal, and VGA Pocket PCs like the Axim. The EDGE radio is a full 2 generations behind the state of the art. Cingular’s fastest network speed requires HSDPA support, as seen on the Cingular 8525 mentioned below, which provides 25KB/s+ upload speeds - far in excess of anything EDGE can deliver. But, the iPhone is sex on a stick, and sure to sell by the 10s of millions.

So, apart from it not having a card slot, any other problems? Will the iPhone actually allow 3rd party applications to be installed? I didn’t see this confirmed anywhere. It would be disappointing if they lock it down, but not without precedent.

UPDATE:
David Pogue has posted a list of FAQs, and I`m afraid the answer would appear to be no, Apple will not be allowing 3rd party apps to run on the iphone.
