iOS 4.1 Restores Field Test Mode
Gizmodo reports that iOS 4.1 has reincluded the Field Test mode to iOS. Field Test mode allows you to get a numerical figure for your antenna strength rather than the traditional bar measure. To get to Field Mode:
- First, upgrade your iPhone 4 -- or any iPhone -- to iOS 4.1.
- Dial *3001#12345#* into your phone [and press Call].
Most customers won't care about their numerical signal strengths, but the antenna strength changes generated a lot of publicity surrounding the iPhone 4 launch due to issues with new antenna system.
