I downloaded the software, and followed the instructions set forth by cell-tracker. Nothing on my phone, tried the download twice. Up to 4 downloads or 48 hours, well after nothing with the two separate downloads, I figured why not try again... 30 hours later my time had run out. Hmmm... 48 was what I read. Not to worry I was fool enough to purchase the warrant for future downloads at an additional cost. I haven't registered my warranty, because I'm sure it won't help. About like the no phone/email only tech support was no help. Or should I say no response? All under the no refund policy. I fell for the trick do yourself a favor and shop elsewhere.
