Steve Jobs announced the long awaited iPhone 4 Tuesday and it looks like a really great hardware and software update.

Here at CarCheckup we’ve asked ourselves if now is the time for the iPhone to overtake personal GPS devices like TomTom and Garmin as rulers of your dashboard navigation.

Here is our staff breakdown based upon the specs of the yet to be release phone:

The Good!
    No additional device to carry – It’s nearly always with you when you need it.
    Extended battery life over the iPhone 3GS – You’ll still want to plug into a car power adapter.
    Higher Resolution Screen – Sharper screen = less eye strain and sharper graphics
    Multi-tasking – Run your Navigation application and other apps at the same time
    Better Antenna – Case integrated antenna with and glass front & back should help GPS accuracy

The Bad!

    Small-ish 3.5 inch screen - smaller than the typical Personal Navigation Device
    Longer trips will still need a power adapter – .
    Big name GPS apps cost nearly as much as a stand alone GPS
    Less speed/Accuracy than a stand-alone personal GPS – It’s yet to be seen if the iPhone will be able to hold it’s own vs. stand alone GPS in terms of update speed and accuracy.

The real question becomes…What will software developers do to maximize GPS applications abilities on the new iPhone 4 platform?  We’re as anxious as you are to find out!

Preorders for the Apple iPhone 4 start on June 15th.  iPhone 4 deliveries start on 24th.
