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].
Pressing Home will exit you from the Field Test mode. For reference, Anandtech provides a good discussion about bar strength and signal values. Since that article was published, Apple has remapped the signal strength to # of bar ratio. More negative numbers are worse, and Anandtech reports they were surprised they were able to hold calls with signals as low as -113db.
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.

Bloomberg's Mark Gurman expects the laptop to arrive between late 2026 and early 2027, with the later window now looking more likely owing to the global memory chip shortage. Analyst Ming-Chi Kuo expects mass production to begin by late 2026.
