So, every person who buys a ticket to ride the train should snap a few random pictures with their cell phone. Then rinse and repeat each day. Eventually, the cops would become conditioned to this and view it as normal. Much the way their gradual assault on our rights and freedoms is becoming normal to us.
I have an iPhone 4 and do NOT experience any signal drop when holding it. I've held it in my hand covering every single joint between the three antennas and no change. I am unable to duplicate the issue.
Have you asked to have the fees covered? When my company began asking me to handle areas of the business that I wasn't prepared for I requested a graduate degree so I could gain the skill set. They agreed to pay for tuition. I would pay for books and attend class in the evening. I could study whenever so long as I got my duties done. I would not sever employment or get fired for negligence for 2 years after receiving a reimbursement check or I would pay back 100% from 0 - 1 years or 50% from 1 - 2 years. Also, reimbursement was based on performance; 100% for an A, 80% for a B, and 50% for a C. My company was concerned I would take my new skill set and shop around for new employment so the agreement give them some protection and a chance to recoup their investment.
Couldn't you just use a silicone fluid like Dow Corning 200 Fluid? It's available in a wide range of viscosities to suit your pumping, flow, and evaporation requirements. We use it as a medium for Dk and Df testing on microwave lamiantes. http://www.dowcorning.com/applications/search/products/?Ntt=200&N=0&Ntx=mode+matchany&WT.svl=3&Nty=1&Ntk=ProductFinder_en
