I ordered for the unlock solution for iphone 4 4.2.1 on the website http://myiphone-unlockwizard.com
The solution provided on the site is available for free everywhere on the net. By the way it does not work for the iphone 4 4.2.1 with baseband 3.10.01
After trying to contact the websitehttp://myiphone-unlockwizard.com repeatedly, no response has come from them. So I have filed a complaint with Plimus, the payment gateway.
As such, I understand that unlock solution to the iPhone 4 4.2.1 baseband 3.10.01 is not available right now and once its available it will be available for free.
Readers are advised not to fall prey to these sites and do a thorough search on the net and get the solution for free, istead of paying $30 for something that's available for free!!
