Aside from the screen sizee and keyboard, are there any significant differences between the two??

I recently did a comparison of the 8130, the 8830, and the 8330 (Curve):

Hopefully it will help a little.

There is more memory on the Curve.

I switched from the Pearl to the Curve. I miss the size of the Pearl, but really, the Curve isn't that much bigger. I am really enjoying all the shortcuts from the home screen if you have dialing from the home screen turned off. I.E.: pressing "U" to get the calculator, "B" to get the browser. Really makes accessing programs easy!

Get the Curve (8330), unless you really need a world-phone (8830).

I like it for these reasons as well

Oops... I meant to say the 8330 curve instead of the 8830. I placed the order on sprint.com but at the end of the process is stated the 8330 is on backorder. SUCKS!!!!!!!!!! Anyone know how long it usually takes?

just walk into a Sprint store. *title updated for 8330*

Let's also mention that Cnet ranks the Curve by Sprint as one of the Top 10 Phones with Highest Radiation

And here I thought I just had a glowing personality.

Big difference between the two as far as I am concerned.
