I have a flip phone but I'll bet money on saying it gets better service than your smartphone phone AND it will last longer.
Did I mention that I overclocked my phone from the stock 350MHz to almost 600MHz. My apps and games run much faster, and surprisingly my battery life is better then it was before. My guess is it has to do with my phone not running the processor at full speed as long because the programs load almost instantly, instead of taking 15-20 seconds.
