Apple iPhone 4 (32GB - black, Verizon Wireless)

Pros: +Solidly built product
+Good user interface
+Calls do not drop

Cons: -Data speeds surprisingly slow
-Signal often weak (in Wash DC area)
-Certain basic functions you should be able to do on a smartphone without paying for an app (especially after having dropped $300 for this device)

Summary: A solidly built Apple product with a nice user interface on reliable Verizon network. However, that reliable Verizon network also has painfully SLOW data speeds at times and doesn't always have a very strong signal.

I've been a Verizon customer for over 5 years and have generally been pleased with their network. Prior to purchasing the iPhone I had a basic flip phone that I rarely used for any data needs. It was used almost exclusively for voice calls. I considered jumping over to ATT when the iPhone initially came out, but the constant rumor that Verizon would "soon" be getting the iPhone kept me with Verizon -- then it actually happened (albeit 3 years later). So I was more than happy when this was announced and placed my order promptly. With my new iPhone in hand I've been mostly pleased with the performance (I had a 3 gen iPod Touch prior to this and was familiar with the interface and functionality).

That being said, there is one consideration that should weigh pretty heavily for any user considering a Verizon iPhone vs. an AT&T iPhone. And that's data speed. I've never been a customer with AT&T but have friends who have an AT&T iPhone. My experience has been when using data apps on their phones (surfing the web, using maps, or any app that requires downloading/uploading data) it is a pretty fast connection. However, I've found on numerous occasions (this is especially true when using maps or navigational apps) my Verizon iPhone has been painfully slow - if not totally ineffective. Needless to say, I'm pretty disappointed having waited this long for iPhone to come to Verizon only to find their data speeds are mediocre at best. I know AT&T has the dropped call issue so I guess you have to pick which poison is more tolerable.

Bottom line, Verizon doesn't drop calls but their data speeds kinda suck - which is a significant issue. So the question is do you want to suffer lame data speeds (Verizon) or dropped calls (AT&T)? You shouldn't have to suffer either one, but if you want an iPhone those are currently your choices.
