I moved home on Tuesday, and discovered that I get very low or even no signal in my apartment. I was wondering if there was any way to improve signal in my apartment? I have heard about signal repeaters, but they're too expensive. I did download an app from the market called 'Signal Booster' but it doesn't seem to help. This could possibly be an impossible question to answer with the options I have, but does anyone have any idea how I can improve my signal? Thanks P.S. I have to put my phone in a certain area of the window ledge, and use Barnacle WIFI tether to get online. I get a HSDPA signal there.
