Here’s how I activated my SIM/hardware-unlocked Android Dev Phone.

1. I popped the SIM card out of my AT&T Go phone (cost approximately $20 at Target).
2. I made sure that there was some $$ on my Go phone account.*
3. I followed these instructions to activate the phone.

Why did I activate my Android Dev phone with a pay-as-you-go account?

My initial desire was to have a device that I could put apps on and test the apps as a user; however, now that I have the phone unlocked, I am thinking that I will want the phone as my primary phone. We will see; I am so indecisive about this phone. One reason that I can’t decide what to do is that I am on Verizon (CDMA); the G1 runs on 3G on GSM, but not at the same frequency as AT&T 3G network. So, in order to run the G1 on AT&T, I would have to run it on EDGE, which is slower than the 3G. So, I may end up switching to T-Mobile anyways… they have a nice flex plan that doesn’t require a 2yr commitment or your SSN.

*I believe I had $25 on the phone when I activated the phone. After about an hour of web surfing and email checking on the phone, all of my minutes/KBs were used up. :(
