Hey guys, my dad has a 2G and he's kind of apple unknown if you will, but he is complaining because his 2G will not show an incoming call unless he actually hits the home button and sees the person calling, and or the missed call. Apparently this is a hit and miss situation. Same with texting, sometimes he gets it right away, sometimes 5 hours, sometimes never. Is this just a carrier issue or something wrong with the phone? He's paranoid because I bought it used 3 months old from someone. Thanks.
