iPhone with 3G capabilities is slowly but definitely becoming a reality as more and more sites seem to be finding leaked images of the handset. With all the hullabaloo of Vodafone bringing the iPhone to India, things could be looking up for Apple fans. It seems like it would probably have a more glossy finish and it also seems like the Dock/Speaker connectors might also be altered slightly.

Apart from that the next-gen iPhone could also be sleeker. Not that it isn’t already, but there’s always room for improvement.
The 3G version aside, Apple has launched the Beta 5 version of the iPhone SDK. This newer version will supposedly make things a lot easier for developers by making the existing tools a lot better and it should also be able to fix a few more bugs. The new SDK includes a set of tools like Xcode IDE and Instruments analysis tools as well as compilers, frameworks, and documentation for creating iPhone OS applications. It also has a test simulator to test the created applications.
