Normally I would get 5 bars 3G reception on my ATT iPhone, but for the last couple of days something is interfering with my reception. During the day the iPhone would get 1bar 3G and often revert back to 1-2bar EDGE. Its so flaky I can't even browse or check email. I also notice my computer speakers would go wonkers doing morse code rather loudly. My iPhone isn't even near the computer. Not really sure if my iPhone is causing the speaker to buzz or the interference in the area. At night time everything goes back to normal. I get full 5 bars 3G and able to get 8-9Mbps downstream. Could it be atmospheric issues, someone operating radio equipment during the day near my area or ATT towers?
