Tsaico: he has the 7 percent off because he has the W-2 benefit discount...
otherwise, the AT&T (GSM, new one) is 39.99 for 500 anytime and 1000 unlimited. Do not get the TDMA (old) AT&T (I don't think they even allow any more subscription for that)
anyways, Tsaico, you may want to ask brtspear2, dc, NuclearFusi0n1 (they all ATOT-er in UCR) and other Cell phone users in your area and see whether which Service provider has better coverage.
I would stick with either ATT GSM or Cingular or T-mobile (which the latter two will merge together)
Nextel is too expensive for personal use, it doesn't justify for the cost unless your company has a lump, corporate plan.
