I bought an iPhone4 on launch day and also have a nexus one. I haven't used the Nexus since the iPhone 4 came out since I don't have a micro sim adapter. I plan on ordering one soon so I can continue to use my nexus 1. Anyone else using both and can recommend a micro sim to normal sim adapter? Also, am I playing with fire everytime I put my sim into my nexus 1? I really don't care to lose my unlimited plan.
