I'm curious as to just which iPhone exactly TiPb readers are rocking these days. Have a lot of you upgraded to iPhone 4? Is iPhone 3GS the most common? How many find iPhone 3G or even the original iPhone 2G perfect for their needs? And if you don't have an iPhone, which alternate iOS device are you using the most, iPod touch or iPad? And if you have multiple iPhones or iOS devices, just let us know the one you use the most, your daily driver.

Vote up in the poll above and then give us the details in the comments below!
