Did speedtest on iPhone 4 using speedtest.net app.Just got sharp 0.2 Mbps download and 0.3 Mbps upload speed Time 12:20 pmWhen the phone was kept in the same spot on desk today morning, I got 2.20 Mbps download and 0.40 Mbps upload. Time was 8:00 am.This is definitely a traffic congestion issue. I bet many people in my area (Dadar/Prabhadevi) have jumped on Rs. 4500 plan.
