For everyone that is complaining about their phone's signal issue.... Why don't you just buy a case for it ( not a bumper, but a proper case) ?
Look at it this way.
1 - The iPhone is fragile, one accidental drop on a hard surface is going to cause some damage.
2 - A case will solve your signal issues, so you can hold it anyway you want and not have to worry about anything.
A $30 investment for a $600 phone is a pretty good deal, and guaranteed that the day you drop your phone without a case and the screen cracks, you are going to be wishing you had purchased that case in the beginning.
