Well, kind of. With the new Sprint ad claiming that with it’s small 4G mobile hub, you can enjoy 4G internet speeds, which it claims to be almost 10 times faster then the current AT&T 3G speeds. Practically that would make your iPhone 3G/3Gs into iPhone 4G in no time!

Sprint claims that iPhone users can enjoy 10X faster internet speeds with it’s Overdrive which is actually a mobile 4G hotspot. The ad clearly targets AT&T’s crappy service during rush hours and holidays.

Here’s the “iPhone 4G” ad from Sprint:

Note: This is not the iPhone 4G that Apple will release pretty soon. It just aims at giving 4G speeds to your iPhone 3G/3Gs
