Apple site says the latest software update for 3G phones are 4.2, is this true? Anyway I can update to 6.0.1 to install Instagram?
Update iPhone 3G to iOS 6.0.1?
They stopped updating to 3g a long time ago
Well Apple's own website wouldn't lie…
The iPhone 3G only go up to 4.2.1. No way to get 6.0.1 on it. You'd have to get an iPhone 3GS at least to get that version.
That hardware is too outdated, dont update it. Only 4 or later.
Unlock it, then try
