The A5/1 crack is not a theory, it's a reality and those guys in that link demonstrated this sometime last yr. However, what was apparent was that to achieve an actual tap is a very complicated and expensive affair, so much so that to exploit it in any meaningful way would require organized entities with unlimited resources (such as government security agencies). Infact, not far fetched conjecture
within industry circles has always suggested that all the current A5/* GSM ciphering algorithms were cracked long ago by some agencies (Mossad is a prime suspect), its just that it's not in the public domain.

actually its not just androids and Iphones, any phone with gps can
'track' you...Im not sure how much info you need but: but the US
several years back made it a requirement that cellphones making 911
calls also send their locations or have the ability to avail it, this
was built into the baseband processor - the specs were defined on 3GPP
TS 04.31. the specification was called RRLP - radio resource location
services. http://en.wikipedia.org/wiki/RRLP

Unfortunately for you, this communication is not authenticated. RRLP
is to say the least one of the most dangerously open protocols out
there -  gsm (well the baseband processor) is full of them -.
fortunately for you, people/governments are not interested in hacking
gsm networks and phones yet...if you're a criminal however....just use
that torch with a phone:-)

Apple and Android probably just have apps sitting on top of this, but
all gps enabled gsm phones are a risky affair...steve if you need more
details on the baseband processor/gps and maybe a few papers you know
where to reach me..
