Apple's plan to keep the next-generation iPhone a secret isn't going too well. With two handset leaks (the most recent one just last week), the company seems to be having trouble keeping its component makers quiet too. Indeed, Digitimes has spoken to a few to get the lowdown on the hardware likely to appear in the iPhone 4G.According to the publication, Apple's new smartphone, which is due to be unveiled in June, will have twice the RAM of the current model, bumping up to 512MB of Samsung-made memory, which should make the promised multi-tasking a breeze. There will also be an Arm Cortex A8 processor and for viewing your apps, an LG-made touchscreen with a 960 x 640 resolution, twice the resolution of the current iPhone model.Ok, here's the science. According to Digitimes, the handset will offer IPS (in-plane switching) panels with FFS (fringe-field switching) technology, the latter providing a wider viewing angle and clearer visual quality under in sunlight. So better for reading. Reason? Apple wants to promote e-books on the iPhone, so a good screen is paramount.The panel is also 33 per cent thinner than in previous iPhone versions, which means more room for a larger battery module, which means a longer battery life. We like that very much.All of which should mean a huge demand for the phone when it lands in a matter of weeks. Apple has that covered too. According to the report, iPhone manufacturer Foxconn is preparing to ship 24 million next-gen iPhones from next month, with 4.5 million in June alone. So camping out all night to get one might not be necessary for you early adopters. Is it all true? We suspect so, but we'll have the lowdown on June 7th separating fact from fiction at Apple's official launch.
