I'm also intrigued by the thought of staying with AT&T and getting a Skyrocket. I hate the thought of losing my unlimited data by switching to Verizon. And, of course, there's always the messy situation of switching phones when traveling abroad.
With that being said, I'm not sure I'd be able to tolerate the 800x480 resolution after coming from an iPhone 4. It's too bad they didn't release the Skyrocket as the HD LTE GS2.
Also, as an aside, I just called my local Verizon store to make sure the associate I bought my Galaxy Tab 2 weeks ago from would be there (he's supposed to add my company discount if I bring in a check stub). When the recording answered the phone, it talked about the RAZR for 15 seconds. Then when I got a representative, she answered the phone with "Thank you for calling Verizon Wireless where you can purchase the Razr, the world's thinnest phone, as soon as 11:11 AM tomorrow, so can I help you with any questions about the Razr?" or something similar. They're pretty serious about that phone...
