Answer 1

Jan, did you already find a mapping between the integer value and the signal level in dBm?

Should be something between -113 and -51 dBm for 2G (GSM/EDGE) and -120..-25 dBm for 3G (UMTS/HSxPA).

Answer 2

for testing signal strength u can use this link signal test

It may work for both jailbroken and non-jail-broken.
