Gotta love this phone!
Took the phone down south and walked into an AT&T store. Told them that I wanted the $19.99 100MB of data only (Go Plan) and within minutes I was up an going with no problems at all. No need for any voice minutes, other charges, SIM card fees (they gave me the card for free), etc. $19.99 was all and barely anything for account setup - I think they took my name and that's it.
It was great. Then when I was out an about I had 3G data all the time. Used it for email, a little web browsing, and even a little streaming from the tv.com app. Actually I can't believe I didn't run out and use up my 100MB. I wish I knew how much of that I had actually used.
On the flight home, just popped the Bell SIM back in. It was a great experience.
It makes me sad though that Google closed the online store for this phone. It's probably the best phone I've ever used (yes, I like it better than my iPhone 3GS) but more significantly it was purchased unlocked. This whole process of waiting for the carriers to adopt new models, bastardize them with their custom ROMs, and lock them to their networks is frustrating. My view is that the carriers have us locked into a contract for the subsidy fee so don't also lock the phone! But I'm going off on a tangent. Point is that the SIM swapping was cheap, easy, and instant.
