Engadget just posted information about the next generation of iPhones. Word is that it will have plastic back (not metal), 3G (which is close to broadband internet access), real GPS, a headphone jack that isn't recessed (which makes most normal headphones unusable, annoying!).

No word on whether Flash will be enabled on Safari, that would make the browser much more interesting in terms of running online apps.
Word is it will hit the streets in July. Just when I thought I'd finished buying new equipment this year!
