Was there ever an iPhone called iPhone 2 or was the second iPhone 3G?

And the third was 3GS?

Iphone 3g as it supports a 3g network no there isno iphone 2

No, there was never an iPhone 2. The original iPhone came first, then the iPhone 3G, then the 3GS, and then the iPhone 4 onwards. Hope this helped.

Iphone 3g was the 2nd iphone ever.smh its weird how they skipped #2 out tho

Nope. No "iPhone 2" The 2nd was indeed the 3G & the 3rd the 3GS. The 3G does stand for 3rd generation but in that name it was referring to the cellular data technology, not the generation of the device.

2007 - iPhone*
2008 - iPhone 3G
2009 - iPhone 3GS
2010 - iPhone 4
2011 - iPhone 4S
2012 - iPhone 5

*sometimes called the iPhone 2G to discern from referring to the iPhone in general. Again here the 2G refers to the cellular data technology not the generation of the device.

The iPhone 3G was so called because of the network its designed to run on, the 'S' on 3GS and 4S obviously means 'second edition'

IPhone, iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5
