this is very crazy. after I enabled numeric wifi signal on my 3G, I discovered that it usually showed me the number 54, which I thought was the full wifi signal that the iPhone could receive, even when one inch next to a wireless router.
However, I have noticed that on some routers and ad-hoc networks, I get 53, 55, 56, 57, 58, 59, 60, 61, 62 and 69 units of signal.
WHAT does this mean? is it that the iPhones wifi card could do better? or what does this all mean?
I have screenshots to proove the above if anyone wants them.
(yes, in the wifi menu within the settings app and also on the iphones status bar it shows me those numbers)
