Just wanted to let people know, while using the MicroSIM adapter is pretty easy to use with other phones like Nokias and Blackberries (where one can actually access the SIM tray). Using with MicroSIM tray with the iPhone 3g is a pain in the butt. I got my MicroSIM "stuck" and the tray can't get ejected. I got frustrated and hanked everything out, destroying the plastic microsim adapter plus the iphone plastic SIM tray. Now I gotta go to Home Depot and find a small phillips screwdriver to disassemble the iPhone 3G. On a good note, I went to the ATT store early at 9am, they gave me a replacement microSIM so I can put back into my iPhone 4. They even gave me a 2 additional microSIMs in case I need another one. I told them I needed on for my iPad 3g also and wanted a spare for the iPhone 4. Free of charge. Those guys are the ATT store know me well since I frequent that store a lot. But I feel like an idiot getting the microSIM stuck in my iPhone 3g. It's my sister's iphone 3g so I am using it as a "test unit" iphone touch anyways. Now I am off going to try to disassemble the darn thing to get the SIM that's stuck out.
