"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
As a service technician the litmus paper doesnt lie. I live in Florida and people start talking about humidity and the like. The ONLY reason the paper turns red IS if moisture touched the paper. Be it rain, a babys spit, sweat.. it is still moisture. There has been extensive testing on humidity and moisture with the litmus paper.
