It might help if the cell phone was first wrapped in RF-absorptive sheet or foam, and then wrapped in aluminum foil.  As a ham (callsign N7IJS; oddly, I'm the last "tech-plus" ham in the country due to the refusal of the FCC to act on my January 2010 license renewal application), I am reasonably aware of the technology.  There are probably dissipative ferrite materials embedded in plastic/rubber sheeting which would do a good job absorbing RF.  Example just found with google search: RF and Microwave Absorber - Ferrite Tiles and Foam Absorber    I found that using Google 'rf dissipation ferrite sheet'.

MIT does seem to get around!  (Full disclosure:  I spent four years there, 1976-1980).

I would be happy to reveal any 'secrets' I know, problem is I don't really know any secrets.  I haven't heard of analysis of bio-chem in prison, with the exception of DNA testing near the end of a sentence.  I would imagine it would be possible to analyze the odor of a person using GCMS (gas-chromatograph/mass-spectrometer), and that should be extremely sensitive.  How selective it is, between one person and another, is a question I do not know.  And, of course, a given person's 'signal' could be expected to vary depending on his recent diet, or perhaps whether he has been ill recently.  I have heard occasional references to the idea of diagnosing people of various illnesses based on the presence of minute amounts of chemicals in breath (a neat idea, BTW).
