Im using iphone 4, it was locked in japan, and i had it open line here in the philippines using gevey sim. the problem is there is no option to update the software and i cant download applications with version 4.2.1.
I want to know if I can update my software connecting my phone to laptop, there was a message that ios 6.2.1 is available to download and update my software that there will be no problem with signals and connection. thank you.
iPhone 4, iOS 4.2
