Looks like it's a good day to be a developer for the iPhone. Further to the news that Microsoft is trying to woo people who've made hit apps on the platform for the Zune, comes the revelation that Sony is doing the same thing for its PSP Go.

Pocket Gamer says that developers have been "actively" sourced by Sony to port their games over to the PSP Go. Over 50 have already been signed up so far, and are no doubt banging their heads on the problem of how to convert their games to the Go's smaller display.

Happily, however, the games won't cost the earth. Sources say that they'll cost "1, 2 and 5 Euros", rather than the thirty to forty quid that we're used to paying for commercial games. A low pricing strategy could be the poke that the market needs to finally start buying the PSP in quantity, but we won't know for sure until the console's release on 1 October.
