Has anyone try this?

is the tray thick enough for 2 cards? unlock card and sim

ebay is selling from 15 free shipping and up, does not seem like a great deal

how reliable is this sim unlocking device? remember that antenna extension device that went in the back of the cellphones several years ago that sold for $50? That was a joke.

#2, The 'chip' feels like a piece of ribbon cable, not much thicker than a piece of paper. I have a few other brands of these that do work but the sim card needed to be trimmed on one end for a small chip that protrudes from the ribbon. Also #3 is correct, ebay is the way to go, all three of mine were between $7 - $12 shipped.

What carriers will it work w/ when unlocked? Will any sim card work? Or better: any sites out there that explain this?

Okay, nevermind. I did some research. No go for Sprint.

verizon?

wth is this even legal>??

Who cares if it's legal? This is HERESY!

#9 & #10 You're morons. This is yours. You do whatever you like with it.

only at&t and t-mobile have GSM 3G networks so you got only one other choice in the US.

does not work for verizon

only at&t and t-mobile have GSM 3G networks so you got only one other choice in the US.

"of different countries"... I do believe that this for use in other countries, not other carriers in the US.

i've got at&t, but dont want to pay for the "iphone" plan. Does anyone know if you can use this, stay on the at*t network, and still use the regular voice only (no data) plan instead of having to switch over to the "iphone" plan?

#16 if u have att u dont need this just jailbreak the iphone

www.iPhone3GsimUnlock.com has the solution too. i ordered like 10 from there, tmobile works great. (software solution is the best but...this works too) + does not void warranty

Couldn't get this to work because the guy's fingers which are stuck to it wouldn't allow it to seat into the phone.

#19 - You talking about your johnson or the sim card?
