Best prepaid SIM to use in iPhone

[Alleyoop]

What is the best prepaid SIM to use in an unlocked iPhone 3G? Or even just one that you know works and you kind of like it? Something I could pick up anywhere, like Target..

Thanks!

Not anymore. I got one a few days ago and it didn't work. Some new GoPhone accounts have the SIM locked to the original GoPhone for 180 days. The SIM is supposedly unlockable.

I even unlocked my 3G 3.0 and it still says no service.

This is a new development.
