Lately there have been various rumors going on around the Internet claiming that a 3G model of iPhone is in the works. Clearly we can assume that something fishy is going on inside Apple as the current models of iPhone have been short on supply and iPhones are also no longer available in UK.

It is very clear from the facts that a new model of iPhone is soon coming out and MacRumors has just the report to back this up. As the new Beta of iPhone Firmware 2.0 has already come into the hands of developers, one of them claims to have discovered a feature that confirms that iPhone Firmware 2.0 has 3G support.

The feature is actually a new On/Off option to enable/disable 3G speeds. As it says, using 3G will let your iPhone transfer data on a broadband speed but will consume much of your battery. There is also an option to switch to EDGE to prolong battery life.

Apple is going to keep a common firmware for both of the 3G and non-3G models so those having old iPhone models shouldn’t care much about this new feature. It is expected that the 3G iPhone will perhaps be released on the Worldwide Developer Conference in June.
