Nope, uw ovens use a frequency of ~2.45GHz, which is the resonant
frequency of water.  Microwaves of different wavelengths (such as 900,
1800 and 1900 MHz, as used in GSM cellphones) don't have nearly the same
dramatic effect on water - in fact, water is pretty transparent to most
frequencies in these ranges, *except* for a tight spike of
high-absorbency around the 2.45GHz mark.  Most of the "radiation" from
your cellphone goes straight through your head with virtually no
effects.
