We've just received word that homebrew developer ZodTTD has updated gpSPhone to version 1.5.0. The latest build of this Gameboy Advance emulator for either your iPhone or iPod Touch carries only a couple of new tweaks, the biggest of which is support for Apple's firmware 1.1.3. Here's the rest of the changelog:

* Added support for both scaled/unscaled landscape and portrait view settings.
* Added support for firmware 1.1.3’s “mobile” user. gpSPhone should run well on 1.1.3 now.
* Added hardware accelerated scaling for better performance and look.
* Change from 1.3.0:
* Quick but important tweak to the iPhone video rendering that increased performance quite a lot!

ZodTTD further notes that this new build should be faster and more stable. Full details regarding the manual installation of gpSPhone v1.5.0 to your iPhone can be found in the file bundle's readme. You may also want to visit ZodTTD's original site (via the source link) for further details.
