You've probably seen Verizon Wireless advertising claiming that the company offers "America's Most Reliable 3G Network," a claim that AT&T takes issue with. Verizon has taken the matter to court, after AT&T claimed such advertising is false and cannot be supported. In defending their point, AT&T interestingly tries to conflate network speed and network reliability, given their HSDPA network is supposedly faster than Verizon's EVDO network, and will soon get faster with HSPA 7.2Mbps upgrades:The problem is, while AT&T's HSDPA network is technically capable of faster speeds than Verizon and Sprint EVDO, it it very often doesn't act that way -- particularly in congested networks like New York City. A recent suite of tests by several news outlets highlighted how AT&T's technically faster network quite often under-performs. PC World had this to say in June:Wired magazine had this to say in July:While AT&T seems to consistently believe they're doing a a bang up job, AT&T excels neither in network speed or network reliability, which is why the "Cult of Mac" Is so eager to see the iPhone brought to Verizon. While Verizon might be able to prove their network is more reliable than AT&T's, PC World's test actually found that Sprint had the most reliable network when it came to 3G service. Of course if either Sprint or Verizon found themselves suddenly inundated with iPhone users, they might not be faring much better.
