Well I'm defo not a fan of Windows Mobile perse, but the shell SPB makes beats anything I've seen from Android and Apple. Shame how the "default" setup is the only that ever counts in sales and reputation.
Also there's apparently an iPhone app that interfaces with EQDKP (our DKP site system). It got entered in April, still not approved or something, that's pretty slow....
Interesting link that, I do believe in Apple's model somewhat, keeping the whole store high quality and clean. But it shouldn't take months to approve an app. Perhaps it got denied fast and the EQDKP people haven't bothered telling so on their Facebook/forums etc.
