AnandTech reviews the iPhone 4S

November 13, 2011

This is, without question, the most comprehensive iPhone 4S review out there, and may be the most comprehensive iPhone review ever.

I learned quite a bit, including that you can make the FieldTest strength numbers permanent (the setting persists across reboots) by force-quitting the utility:

[T]o get into FieldTest dial 3001#12345# - you can then keep numerics instead of bars in the top left by force quitting FieldTest after launching it (hold down power/lock until power off appears, then hold the home button).
