Does this device also unlock the iPhone 4? Do you need an unlocked iPhone to use it? My iPhone is a US version which is obviously locked to AT&T. I had to unlock mine with a Gevey Sim. I understand you not being able to cut some SIMs as the cutter doesn't appear to be adjustable. Luckily, the Kolbi ICE sim was able to be cut for my iPhone.
No it does not circumvent security of any type. The solution assumes that the phone is already unlocked.
I ran the Redsn0w jailbreak on my phone to unlock it. However, there are some major drawbacks.
First you Apple claims that this will violate the warranty. However, you can always reset your phone via itunes. But, if this is not an option you might have issues with AT&T or Verizon. I suspect you will have less resitance in the Apple Store with their typical can do attitude but it still is a risk.
Second is when a new version of IOS software is released for the phone you need to wait before upgrading. Upgrading will always set the new IOS operating system without the unlock or the jailbreak. You need to wait until the jailbreak exists before upgrading again.
While 10% of iPhones do have a jailbreak it does require some savvy. In my opinion the benefits far out weigh the risks. My phone does everything I would want it to do that apple or AT&T would block for financial gain. I recommend research.
I use to travel with an iPhone 4 clone. But, as others pointed out I already paid a lot of money for the original. The original with a jailbreak provides huge benefits while traveling. One small example is that for around $3.00 USD per month ti skype gives me unlimited calling to the United States over WiFi (I think the vonage app may do the same for free). For a few dollars more per month I also get a US phone number to receive calls and takes a message when I am not available.
With the dual sim modification I am locally available before my luggage is on the belt in Costa Rica.
One other tip I will give you is that once you have a sim card (for any phone) it expires in 60 days unless you put money on it. If you travel to SJO regularly then I would PM Orange for instructions to renew it online for pennies a month. Unless he has already posted it. Orange knows a lot more than he posts about SJO for the tourist.
I could go on and on about the benefits but, I think everyone needs to evaluate that for themselves. It is not for everyone.
