This is my first thread. I will say I am a applecare Sr. Advisor/ Tech support for iPhone/iPad/iPod . Please comment about this: My opinion is the issue of dropped signal for iphone 4 antenna is:Your body has electric impulses, if you touch the left corner of iphone 4 it bridges the two antennas together through electric impulses=dropped signal, the left antenna for BT/WIFI, and the right antenna for UTMS/Cell data. This is a Quality control flaw, AKA A bad batch of phones from foxconn. If it were a design flaw every iphone 4 would have this issue. There should have been a rubber anti-conductor piece between the two antennas: Solution, call 1800MYIPHONE(6947466) apple will replace your phone, or if you want just give you a FREE BUMPER, just ask for a senior advisor.
