The Verizon iPhone 4 is, with the exception of changes to its radios for voice and 3G, only slightly different from AT&t’s iPhone 4. Here’s a list of the differences I learned about so far.
– Radios for CDMA/EVDO instead of GSM/HSPA
– Case has cosmetic differences
– Volume control buttons in a slightly different position
– Cannot be in a voice call while accessing the Internet
– Personal Hotspot (maybe)
Slashgear notes one more difference to add to the list:
Yep, the claim is that holding the sides of Verizon’s iPhone 4 does not greatly increase the probability of a dropped call.
