I have the same problems, and i to can hold the phone with 2 fingers, and it works most of the time. Im told that with the bumper, you wont short out the antenna, and the phone will work flawlessly. I have been using the bumper, and so far seems to have helped the situation.
I would prefer to use the phone out of the bumper. im sure like many of you, i bought this phone because of the design - looks great. i don't want to cover it up with a plastic piece of crap for the phone to work.
There is supposed to be a software update. there are conflicting reports as to weather this update will fix the problem. apple says that it will only fix the amount of bars your phone displays, not the strength of the signal.
not sure what to do.
