I saw a few tantalizing threads (mostly months ago) about an external antenna for the Droid. My lady and I both run Droids and her house is out in BFE where we have to stand in one particular spot to get an SMS message, listen to voicemail or (sometimes) make a call if we are lucky. I thought I could endure having some bloody contraption stuck on my phone when I am out there just to keep connected. Right now our Droids become wifi-dependent bricks when we are there. Are there any of these external antennae around? Has anyone tried one? (and I mean commercial/official products not twist ties or whatever) Thanks!
