Testing on Android Hardware without a SIM Card

I'm trying to test an application on an actual Android device (the main reason is t开发者_开发知识库o test the Bluetooth functionality, which the emulator cannot help with :( ). To help with my endeavor, I'm thinking about buying an Unlocked HTC G1 from eBay. My question is will I be able to use the unlocked phone without any SIM card at all? Ideally, I'd like to be able to use wi-fi and other native apps, but my main focus would be to test my application, without having a SIM card.

If there are any better phones, or alternative strategies that I should employ, I'd be grateful to hear about them.

Thanks in advance!

I develop Android games and have Google's ADP 1 (G1) and Nexus One, both SIM unlocked and regularly used without SIM, not problems at all. Also the former is rooted, while the N1 is not.

I have a G2 without a SIM card that I use for testing, works perfectly, the difference is you wont see some apps in the market. You can either buy an unlocked phone or get a lock one and unlock it for under 10$ on ebay.

you won't have any problems no android phone that I know of requires service to use. I test with my G1 all the time with no sim in it.
