Citing "a programmer at a major software publisher," Kahney adds that the handset should also sport better battery life than the "up to 8 hours" of talk time advertised alongside its predecessor. It will also include GPS and twice the amount of NAND flash memory: either 16GB or 32GB.
What's more, Kahney's tipster claims Apple will allow subsidies on the new model as a means of attracting some of Research in Motion's existing and would-be Blackberry customers.
He points to an article by the UK's TimesOnline, which cites a UBS Investment Research analyst as saying the device could be available in Britain for as little as £100 (or ~$200) beginning in July.
Still, Kahney hedges his bets with a warning that he has not confirmed the integrity of the information offered up by his tipster.
