iPhone SDK 2.1 Doesn't Include iPod touch 2.1 Firmware

If you, like me, have gotten an iPod touch and anxiously installed the new iPhone SDK to scratch your iPhone development itch, you may be disappointed when you start up Xcode and get the unhelpful message:

Unable to locate a suitable developer disk image. Reinstall the iPhone SDK.

And, maybe you do reinstall it, but the message persists. Aaand, when you compile your software, you get a CodeSign error:

No certificate found in keychain for code signing identity 'iPhone Developer'

The problem is that the huuuuuge iPhone SDK 2.1 installer doesn't come with the iPod touch 2.1 firmware image. Suck. Fear not, though: All you have to do is force iTunes to do a firmware restore, which will download the appropriate image. On next launch, Xcode will find it and everything will work great.

Swype's Cool Touchscreen Typing System

Check out this video of startup Swype demoing their new touchscreen typing system. Point at the first letter, and "connect the dots" to each subsequent letter.

The glorious moment in this video is when the guy effortlessly spells "Mississippi" in the space of one second.

Apparently this guy is the/a developer of T9 input as well. The guy knows his stuff, I'd say. The sooner this is present on touchscreen devices, the better.
