It is un believable that in the modern technology available in the marketplace that we see that some of the Giants in the Cell Phone industry are still offering an unsecured network to their customers.

Just last week at a Cell Phone Industrial Show a known hacker was able to show with as little as $1500 he could tap into anybody’s GSM phone, by simulating a Cell Tower.  Back in January of this year a Conference in the Netherlands showed how cheaply a hacker can acheive this.  So who uses the GSM network.. AT&T, T-mobile just name a couple.  However, using the CDMA network used by  Alltel, Verizon and Sprint has it’s advantages today, it’s still secure. 

So we’ll see as time moves on who will take the extra measure to offer a more secure solution in the future..
