Many iPhone users are complaining that this new iPhone 4 has technical problems like screen blemish or discoloration, and signal problems. The iphone 4 signal strength drops when a user holds the phone very tight by the metal antenna band.
Apple’s solution to the problem is give everyone $30 for a bumper sleeve to make these brand new and nearly expensive phones work properly. Use the Bumper or a casing for your new iPhone 4.
