Hello FixYa, Thank you for this great service. I have two questions: 1. Is there a good way to ad tethering to my iPhone 3GS? I heard you have to jailbreak it first and then there is a software app that will enable jail breaking. 2. the battery in my iPhone 3GS no longer holds a long charge. Is there a way to replace the battery myself? Are there instructions to do this? Where can I obtain the parts, battery? Best Regards, Carson

To unlock an iPhone the remote unlock service would be a better option because, you need not give your mobile to someone else nor do you have any chance to enter the wrong unlock codes. To get such an unlocking service for your iPhone 3GS approach Wickedunlock.com and by submitting the country and network to which the mobile is locked to you will be able to remove the restriction from the respective network. This will be a permanent unlocking solution.

The ios 6.1.3 jailbreak made by redsnow is tethered *it means every time you restart the phone you must use redsnow* you should install posixspwn jb ..

Jailbreaking is entirely different from unlocking . Jailbreaking is the process of removing limitations/restrictions so that 3rd party applications can be installed. Unlocking a phone is a procedure to remove any SIM/Network restrictions set on the phone by either the manufacturer of the phone or by the mobile phone's service provider.
To unlock your iPhone 3GS you can get Remote Unlock Service from Mobile-Unlocker.com . There you have to give your Country and current Network name along with your IMEI number to get Remote Unlock Service.
