1. Pathetic and wrong information.2. Just the last page talks about GSM/CDMA stuff, leaving the core (vary basic functionality). Interesting part is that there have been tonnes of references towards finding IMEI numbering which is not applicable in the case of CDMA based handsets. Even that has not been clarified. So if I did not know it, I would still be continuing using *#06# in CDMA handsets, Oh !!!4. There are no probabilities in Security, either that is high state or low, leaving absolutely no scope to go to tri-state mode.5. No mention of intented audiences: Frankly speaking for technical people, its totally dump.6. The author has used the word "basically" in every other sentence and overall usage has gone in thousands.
