Many of the iPhone's long-awaited features will finally become reality Wednesday when Apple rolls out iPhone OS 3.0.

Current iPhone owners can download the software from iTunes for free, and iPod Touch users can get it as well, but for a fee of $9.95, just like the last OS update. What time exactly, we don't know yet. Apple will only say iPhone OS 3.0 will come out sometime Wednesday.

Of course, iPhone 3G S will do some of the above.

When the iPhone 3GS was announced on Monday, Apple didn’t tell us what the exact hardware specifications for the latest iPhone were, luckily T-Mobile in the Netherlands has leaked the info, on top of the 3.0 megapixel camera that we already know about, the iPhone’s internal memory has been increased from 128MB (iPhone 3G) to 256MB.
